ThumbnailPluginThumbnails for everyone | ||||||||

The thumbnail's size will be determined from the preference variable THUMBNAILPLUGIN_SIZE, which defaults to 150 (pixels). | ||||||||

> > | The preference variables can be set in the containing topic, your home topic, the containing web's WebPreferences topic, or the site WebPreferences topics. If a preference is set in multiple places, the value closest to the topic using the plugin will be used. | |||||||
Use multiple sizes for accessibility as well as for esthetics. However, they do take time to generate, so don't go too wild. | ||||||||

< < | Used with the AttachLinkPlugin and ImgPlugin, it becomes easy to do things like display hyperlinks to images as thumbnails of that image. Examples below. | |||||||
> > | Used with the AttachLinkPlugin and ImgPlugin, it becomes easy to do things like display hyperlinks to images as thumbnails of that image. Examples below. But if that's what you want, use %THUMBVIEW instead.
Note that the THUMBNAILPLUGIN_ENABLE preference controls thumbnail generation on upload; it does not control expansion of the %THUMBNAIL and %THUMBVIEW variables.
%THUMBVIEW{ name="filename" variant="size" topic="topic" web="web" caption="string" cpos="position" align="string" border="" height="" width="" id="" class="" link="filename" ltopic="topic" lweb="web" fullpath="" }%
This is a lot simpler than it looks, as all the defaults are reasonable.

This plugin requires the GD and Image::MetaData::JPEG libraries from CPAN. | ||||||||

Of course, neither of the previous methods support multiple sizes as easily, nor are they as well abstracted from the attachment implementation. | ||||||||
Added: | ||||||||
> > | The easiest, and recommended use is:
%THUMBVIEW{"foo.jpg"}%
This will display a default sized thumbnail of foo, making it clickable to the full-sized version.
%THUMBVIEW{"foo.jpg" caption="foo revealed"}%
is about as complex as is ordinarily needed. | |||||||
Plugin SettingsPlugin settings are stored as preferences variables. To reference a plugin setting write%<plugin>_<setting>% , i.e. %NEWPLUGIN_SHORTDESCRIPTION% | ||||||||
