I really don't think my problem is with Sigpics if the is what loading a image from your computer files, these 4 sigs are all [IMG]Codes[IMG] I believe sigpic you can only upload 1 image I will have to check that

Well, my post explaining how signature permissions work still applies.

Can it be fix?

Have you tried running, Maintenance --> General Update Tools --> Empty Signature Cache

If you have made changes that affect the output of signatures, you may use this to empty the cache and force signatures to be rebuilt with the new settings.

Does this really help? As far as I know, this only rebuilds existing signatures, but does not check for permission changes. But the OP should definietely give it a try.

Can it be fixed? Well, its not exactly broken - it just does not offer the feature you require. Probably one could try to run a cron checking all existing signtures against the current permission set, or try a plugin checking all signatures concerned when usergroup changes occur. But both would not be trivial, given you would have to then block the signatures in some way and notify the user. Simply deleting would probably lead to some very unhappy users (and rightly so).

I am not sure if it is going to help, but it's witch a shot.
