o.k., that is, what I guessed too...
So what other options I do have to make it without a script? Would this be a working possibility:
Step1: Change in ACP to registration without verification mail
Step 2: Add manually all users from the other galleries in ACP with their mail address one by one
Step 3. ??? How to copy their password? with copy/paste of mysql table? Or can I force them to get a random password that they have to approove?
Step 4: upload in ACP the images to the corresponding username
Step 5: ??? How to get their albums in the new install?
Step 6: ??? How to get the comments over? Impossible?
So step 3, step 5 and step 6 would be with this procedure my headache..
Any ides how to do that? Any better/easier way to do this without a script?
