Simplify/Robustify thumbnail usage for template designers
Description (last modified by )
This is pre-work for the PDF media type handling which is supposed to show default pdf fallback icons in the beginning.
Please consider merging the branch get_thumb_url from my git repo at git://gitorious.org/~spaetz/mediagoblin/spaetz-mediagoblin.git.
Description of my change straight from the commit log:
Simplify/Robustify the thumbnail URL usage in templates So far templates required a very complex blurb to simply insert a thumbnail URL, exposing much of the internal logic to the template designer. In addition, we would fail with an error if for some reason the media_files['thumb'] entry was never populated. This adds the MediaEntry.thumb_url property that template designers can simply use. It will do the right thing, either fetching the proper thumbnail or hand back a generic icon specified in a media's MEDIA_MANAGER as "default_thumb". Add an image default fallback icon (stolen from Tangos, which are Public Domain since version 0.8.90 as I understand) since the one we referred to was not existing. Perhaps, a "broken image" icon would be better, but I'll leave that to our capable designers. All templates have been modified to make use of the new thumb_url function.
