annotate weblinks/views.py @ 645:99f7917702ca

Fix 081a88b3bfc8, javascript resize of forum images. Commit 081a88b3bfc8 broke those pages that loaded forums.js but did not load the imagesLoaded jQuery extension. Now we have arranged it so that only the forums topic view loads imagesLoaded and put the resizing javascript inline.
