I would like to restrict the commenting function through the comment widget. The possibility to write a comment should only be seen in the folder view (you can see the overview of the photos in the folder). The individual photos themselves should not be able to be commented on.
In a skin like Minimal, which produces individual slide pages, you could hack the skin - turn off the automatic widget injection, then call the widgets explicitly in index.htt, but not in slide.htt.
But in a lightbox skin like Tiger, when you're viewing the individual images, you're not leaving the page of thumbnails - it's still there, hidden by the image viewer. The widget code has already been called - it's a bit late to unring that bell.
The skin would have to somehow turn the widgets off when you click on a thumbnail, and turn them back on when you close the image viewer. Maybe Laza could figure out how to do that. It's certainly not something a user could even begin to tackle.
If the user minimizes the widget bar, it's replaced by just a "+" on the right, and the album remembers that choice for a while. The skin is not controlling that. When I visit your link for the first time, the full widget bar is visible, unless I minimize it.
Don't understand what you mean about "folders that contain photos and not more subfolders." A folder is a folder is a folder. The widget code doesn't know the difference between "top level" and "subfolder." They're all just index.html pages, whether they contain photos, subfolders, or some combination.
Again, the widget code doesn't know or care what's on the page. That page might have folders, might have photos, or might have folders and photos. It has no way to figure that out, especially since every skin codes the index pages differently. There's no "marker" that can be used to determine what kind of page it is.
