I will open up a new Album with some photos and I'm searching for the best way that some other viewers can add their own photos when they have some!
That would save me a lot of time and give people the direct way to publish their pictures without the long way over me.
Is it possible with jablum?
and if it is not possible with jalbum, can you give me an hint which way I can achive my goal?
Not possible with jAlbum. jAlbum is purely client-side. You choose images from your PC, make an album with them, then upload the album. On the server side, the server simply presents the album pages to the visitor - there's no server-side processing involved, so your visitors can't change the album in any way (nor can you - if you want to change it, you need to make the changes on your PC, then upload the new version of the album).
Not sure what else to suggest - allowing site visitors to change the content of a site is usually a minefield of problems.
