Image-Specific Settings

To access image-specific settings, hover on a thumbnail in the main jAlbum editing window, and click More.

Then choose Edit.

Then choose the Pluto panel on the right side of the editing window.

Info: Video Support

In Pluto, support for videos added to an album project is dependent upon the video support built into jAlbum. For videos to work properly in an album, video support must be enabled in jAlbum under Tools (jAlbum in macOS), Preferences, Advanced. The slide window that displays the video will be the same size as the video's native dimensions, unless you specify other dimensions (see Image-Specific Settings). If those dimensions are larger than the image bounds chosen under Album » Settings » Images » Image bounds » Images, the display will be reduced to fit within those bounds, preserving the aspect ratio. The actual video file in the album will not be adjusted - only the display window is scaled down as necessary.

With video support enabled in jAlbum, the core program automatically provides a thumbnail image for the video. In image editing mode, a slider is available to choose a video frame other than the one automatically selected. This can be especially helpful if the video starts with several seconds of a black screen - the automatically-selected frame might be black in that case.

It is possible to provide your own representing image for the video, which could be an image that doesn't even appear in the video. Choose a full-sized image (a regular JPG file, and not just a small thumbnail), change its extension to .thm, and give it the same name as your video. For example, for a video called mydog.mp4, the image file should be named mydog.thm. This file should then be added to the album project at the same time the video is added to the project. This image will then be used both for the thumbnail and for the video frame while the video is loading and after it has finished playing.

Pluto can also support externally-hosted videos from YouTube and Vimeo. To use this method, see Info: Hosted Videos.

Your web host must provide video files with the correct header information. The MIME type must be video/mp4 - if an MP4 file is delivered by your web host with any other MIME type, playback will fail in some browsers. If you find that a video in your album plays properly when you preview the album locally, but displays only an error message when viewed from your web host, an incorrect MIME type is the most likely cause. Ideally, your web host should correct the server configuration, but if you can change your own .htaccess file on the server, adding this line will correct the problem:

AddType video/mp4 .mp4

In addition, video files must not be compressed by the server using something like gzip, for example.

Info: Hosted Videos

Pluto supports the display of videos hosted on YouTube or Vimeo.

jAlbum does not have a way of extracting a still image from an externally-hosted video to use to create a thumbnail for it. You can use a video editing program to extract a single frame, take a screenshot, or choose any other still image to represent the video in the album. This should be a full-sized JPG image, rather than a thumbnail.

Add the image file that represents the video to the album project.

Because the video must be connected to a single image, you cannot use album-level settings. You must choose the settings for this video under Image-Specific Settings. jAlbum cannot determine the dimensions or the length of an externally-hosted video, so these values should be entered manually. Enter the absolute URL for the video.

For a YouTube video, view the video on the YouTube site, and click the Share, then Embed links. If there is no Embed option, that means that the person who posted the video does not allow it to be embedded on any other site, and you will not be able to use it in your album. Make note of the width and height of the video, then copy the URL that's shown in the embedding code (use CTRL-C to copy it, then use CTRL-V to paste it into the Pluto settings, to avoid errors). The skin will accept any of the following URL formats:

For a Vimeo video, view the video on the Vimeo site, and click the Share icon, then click the Embed link. Make note of the width and height of the video, then copy the URL that's shown in the Link box (use CTRL-C to copy it, then use CTRL-V to paste it into the Pluto settings, to avoid errors). Do not include any autoplay parameters - the skin will take care of this automatically. The skin will accept either of the following URL formats:

Info: HTML Tags and jAlbum Variables

HTML tags and jAlbum variables may be used in a number of different contexts, and will be honored in the album (including things like links). jAlbum variables will be passed to the jAlbum engine and will be evaluated before they are placed in the completed album. Almost all user entries are treated in this manner:

If you use a < or > character in a text string, it is assumed to be part of an HTML tag, and may produce errors if it isn't. If you want to use one of those characters as simple text, use its HTML entity code, instead.

Info: Google Fonts & WOFF Files

A longstanding problem with web pages is that fonts are not actually included in the page code. The page simply includes some text, along with an instruction in the CSS that tells the browser what font to use to display that text. But if the visitor's computer doesn't have that font installed, it falls back to a default, or works its way down whatever font stack is indicated in the CSS until it finds a font that it can use. The effect of this limitation is that web page designers are generally forced to rely on a small set of "web safe" fonts, fonts that can reliably be found on most visitors' computers.

Packaging fonts with web pages in a way that allows the site visitor to install the font on his computer, while possible, runs afoul of copyright protections. Most fonts, even those normally distributed with a new computer, are protected by copyright, and you don't have the right to make them available to others.

To address this problem, Google Fonts and Web Open Font Format (WOFF) files can be used. The font is not actually installed on the visitor's computer. It is used only for displaying text on your web page. Google Fonts and WOFF files are now supported in almost all current browsers.

In Pluto, you may add a Google Font and/or a WOFF file, and tell the skin which font to use for each text element, with the default being the selected regular font family. Decorative fonts can be difficult to read at smaller sizes, and are therefore best used only for page titles. You are likely to find that they look better when displayed with a larger font size than you would use for a regular font, and with normal weight, rather than bold. More traditional fonts may be suitable for all text.

To choose a Google Font, visit the Google Fonts page, and identify the font you want to use. Make a note of its name, and enter the name in the Pluto settings. Pluto does not support the use of Google Font multiple styles. If you see a font listed, and it indicates that there are multiple styles of that font available, when you enter its name in the Pluto settings, the skin will use the basic style of that font.

There are now many hundreds of free WOFF files available. Search the web for free woff to find sources (some sites require registration). In most cases, the fonts are free for you to use on your website, even if the website is commercial, but the font designers retain copyright, so you don't have permission to redistribute the files directly to others. Often, these free fonts are provided in a variety of formats - WOFF, OTF, TTF, EOT, SVG, and so on. The format needed for Pluto is indicated by a .woff file extension. In many cases, the download will be provided as a zip archive containing several formats - you need to extract the .woff file from that archive and use that one for inclusion in the skin.

The FontSquirrel site is a typical example, offering many free fonts. Find one you like, and then click on the name of the font (not on the Download link). Then look for a Webfont Kit link on the menu bar. There, you can choose the WOFF format. If a font is available in only one format, the Webfont Kit menu bar choice will be absent. In that case, you can download another format, like TTF, then use FontSquirrel's Webfont Generator to upload the TTF and convert it to WOFF - choose the Expert radio button after you've uploaded the TTF version. In short, it may take some exploration to find the WOFF file you need.

See Fonts » Album Fonts to include a Google Font and/or WOFF file in your album.

Info: Master Album

With almost any skin, it's possible to create folders and subfolders, and produce a multilevel album. But in most cases, all levels must use the same skin, and usually the same style of that skin, as well. Pluto, however, can be used to create a master index of other albums; each album may use a different style of the Pluto skin, or a different skin entirely.

Info: Version Updating

New versions of Pluto are published with some regularity. These new versions generally include new features, improvements, and bug fixes. The jAlbum application will let you know when a new version is available, and users are encouraged to download and install the new version.

Info: Browser Support

Pluto produces albums that display properly in most browsers.
