Neptune. Now launch jAlbum. Choose
Neptune from the list of skins on the lower left. Now add a few dozen images, give the test project a name, and make an album.
Don't expect the default settings to do exactly what you want every time. I choose defaults for what I consider the
best quick results, but almost everything can be changed. Thumbnail image bounds, fixed shape thumbnails or not, page width, etc., etc. The options are endless. But they all work.
On any panel in the skin settings, the ? in the upper right corner will always take you to the user's manual page for those settings.
Advance warning: there are some things my skins just don't support, and never will. No shopping cart, no social media, no search function. The first two, because they're the
Black Hole of Maintenance, and the third because that requires JSON-driven albums, which always seem to be buggy as hell. I won't do them.
When you open an existing project, it will always open it with the skin that it was saved with. And you don't want to start experimenting with choosing a different skin for a large, existing album. Always do your playing with a test project.
