jAlbum produces only client-side web pages. Forms aren't of much use unless they include server-side functionality, so this would be a fairly radical change in the way jAlbum works. In fact, the jalbum.net server doesn't currently permit any server-side processing, for security reasons.
If you're hosting your album elsewhere, you're perfectly free to include some forms in them. A lot of skins provide various ways of including your own content, either as an added page, or as added code on the existing skin templates. Nothing "point and click," of course, but still do-able.
