Dirk there are lots of issues with running the
vb impex system on Photopost users and there is only so much we can do here. I linked you to a script we have to try and assist you in correcting alot of
vb's impex issues but as you have seen like with your multiple user accounts for one user we can not support or correct all issues with
vb's impex script alot of this you might have to correct by hand. This is why integrations are not suppose to be changed so there might be some some work you need to do by hand. There is a script I wrote also if you choose to start over to import photopost users into
vb with the right userid etc.
Want to go from standalone to Vbulletin in Photopost?
I will check out the upload issue but no one has reported this so what version of the software do you have? Is it unmodified?
