You need to see the difference between folders and albums. Folders are on file system level and an actual physical resource. Albums are on logical level and only a construct on logical level that resides on database level. This being said: all http uploads from a particular user go into one particular physical folder of that user. I have no idea if this is the case for JUpload as well: JUpload is not part of coppermine's core, but a user-contributed add-on that doesn't get supported by the dev team, but only by the contributor of that add-on. So what actually is left is the creation of an album where a user can upload to: in the upcoming cpg1.5.x there is an option in coppermine's config where you can specify to have an album created for each user on registration. You can easily backport that feature, as the feature is based on a hack that has been discussed on the board since cpg1.3.x - just perform a search and apply that hack. You need to understand about the impact that this hack will have: for each and every user, an album will be created. If you expect a large number of user registrations, this will mean overkill for the structure within the personal gallery structure: your visitors will be "lost in hyperspace" with so many albums.
Therefore (instead of playing hide and seek) I suggest to actually post the URL of your gallery once it's available publicly and then discuss what you're really up to: tell us what number of users you expect, how fast you expect your user base to increase and what form of uploads you expect. Your question is theoratical, so is my reply. In one posting you claimed to be a staff member of a team being in charge of the site
http://www.johanschultzen.se/bildbank/, on the other you claim to be working on localhost. My Swedish is not that good, but judging from the information available on
http://www.johanschultzen.se/ it seems to me that there is not a large team behind that site, but just one individual: Mr. Johan Schultzen. That has been the case for the banned user moonwiz as well as you. It's amazing that both you as well as moonwiz share the same IP address in Sweden although you claim to be a different person, so the entire story seems very unlikely to me. Instead, it seems to me that you have been banned and that you re-registered using another nick, trying to remove the reference to your site to make sure your reputation doesn't get damaged, as you offer your services as a photographer, web designer and IT consultant. In my opinion that is just a lame effort to cheat, Johan.
