I too have extreme concerns about the reduced size limitations currently imposed post-revamp. As a poster of mainly panoramic photos I struggled with the old size lmitations but was able to post work which was of 'adequate' quality. Now I'm sure you can appreciate that the current size requirements are totally inadequate for those wanting to post panoramas.

In light of this highly anticipated 'revolutionary' website update, would it not be fair to expect more rather than less? I personally find it acceptable to have kept the old dimensions and up the 512kb limit. As the previous posters already highlight, Renders competitors offer attractive alternatives should these limitations stand.
