I think the following happens The gif is requested by your page because of the IMG so the GET for the IMG looks something like
http://YOUR_DOMAIN/YOUR_PAGE/bl_red_hundred.gif Now you page assumes this is your activation context and tries to convert it to int (which it's not). I think you can solve this by adding an image Asset. Another option I think would be to not request the image relative to your page but from for example the /images subir (make sure the request if relative with respect to you app root and not absolute). I guess the other problem is related.
