Shiva - remember that the upgrade makes backups of your files in gas/changes/backup so you always have a fresh set - but still - you are right in the fact you should always do a backup before any hack installation (or vB upgrade IMO)
Lizard - thatnks for that - I think making that td width 100% should do the trick. Ill sort in the next package
Shiva (again

) - There is only 1 system default and that is whatever is in your settings. The gas/forums/{forumid} holds as many forum specific icons as you want - that way when a user brings up the gallery, they can choose from the global images, the forum images, or upload their own.
Saying that - I kind of like the idea of having a potential default for each forumid (if one exists)... let me mull that one over.
