Ok, sorry I missed that. Actually I ended up using the piwigo uploader right from the server to the server, worked fast enough to get them all done in a couple hours.

I have the app installed and running well on my web server, but the upload multiple files doesn't work, and it only allows me to select one file. The old stlye upload works but one file at a time unless I keep adding upload boxes.
I have 100 or so photo albums already on this server, is there a way to just move them to some folder within piwigo's app dir? I simply won't be able to use it if I have to import one image at a time.
