acekin, i saw your post in bbpress, does your Tools plug in (non pro, non dev4press) all user image upload like your GD bbPress Attachments does? (i can't find how to activate Tools attachments.) THanK yOU!
I have added two plugins for various functions and uploading pictures is among them. You can limit the file size as well as the number of images that can be uploded. Try:
GD bbPress Tools
GD bbPress Attachments
