I've managed to import my coppermine gallery with all pictures appearing to go in the right categories and the correct info of the photographer attached to each, but no user accounts have migrated properly.
If I click on the name link of a photographer I get the info of someone else and many of the photographers haven't even made it in to the users database.
Click on any of the name links on the gallery and you should be able to see what I mean:
The import should use the same info as your coppermine database... If you didn't have coppermine integrated with your vB user accounts though there's not really a way for it to determine what images were supposed to belong to what vB user...
I'm now back to the situation where all the images are in the right place, with the correct members credited to each picture. The only problem is that the name links for every member either produces an error 'Invalid user spcified...' or it shows the profile of a different user.
This happens on all the member name links, whether they are forum members or not. Also, none of the original coppermine members show up in the forum member list and so they can't login to the forum with the coppermine details.
Sounds like you need a small script/process to go through the Gallery database, look at the NAME, compare it to the NAME in the vB database, and update the user ID in the Gallery database. (Probably can be done with a single SQL statement.)
If you can just keep things as is and submit a support ticket then I can write a quick script to grab the info and have your images updated with the userid associated with each username. This would only work though if the usernames in your Coppermine installation match the usernames with your vB installation.
