is there a way to always fit the proportions of the whole website to the size and the resolution of the viewer/watcher? I use a 4k monitor and when I put everything like I want to see it, the full-HD-viewer will have to scroll alot!
PS: I searched for scaling, but it is always just about the pics but not about the whole site...
If you're actually using online jAlbum, rather than the regular desktop version of the application, you're dealing with skins that are very old, most of them dating from a time when "responsiveness" wasn't an issue.
In the regular desktop version, some of the newer skins are closer to what you're after, like the well-named Responsive skin. But asking for an entire webpage to be scaled to the size of the monitor is a bit unrealistic. If your album has 100 thumbnails, do you really want all 100 thumbnails to be shown at one time, with no scrolling? Even if that means that, on a laptop for example, each of those thumbnails ends up being only a few pixels tall?
