Using FileNodes in templates¶
Although Media Tree is designed to be agnostic of the module you use to generate
image versions and thumbnails, it includes some tags to assist you with
generating thumbnails from
FileNode objects, since this is one of the most
common tasks when working with image files in web applications.
A word about Media Backends¶
Media Tree’s template tags do not use an imaging toolkit directly, but an
abstraction class designed to wrap the actual image manipulation handled by a
third-party module (such as
sorl.thumbnail, to name
two popular choices).
The advantage of wrapping thumbnail generation like this is that Media Tree does
not need to depend on a specific image generation library, with the additional
benefit that you can just use the abstract template tags in your templates and
switch to another
MediaBackend at any time.
