The max image height is 499, max width 499 and max size is 50kb
Apologies if you still have trouble uploading images which fit within the limits. We are aware of a problem, but we are about to implement an entirely new Forum system which should resolve all picture issues.
Unfortunately the new Forum installation itself has hit a problem and will be delayed for a few days whilst that is resolved, so the old system will just have to do for now.
All existing posts will be transferred to the new system when it is implemented.
