...I haven't found where to change it.
The widgets are often misunderstood. They are not part of the skin coding. They're not really controlled by the album at all. You can hunt and hunt in the files that constitute your finished album, and you won't find a single line of code about the widgets.
The widget script is provided directly by the jalbum.net server when the album is viewed, at which point the widgets are, in effect, superimposed on the album. The album doesn't even know they're there. That's why, for example, the skin can't adapt to the presence of the widgets and do something like moving the displayed image up and out of the way of an expanded widget bar - it can't "see" the bar. Generally the best a skin can do is leave an extra 30px of space at the bottom so that the widget bar, in its default one-line condition, doesn't impinge on things like the image and its caption.
There is a limited ability to control a few simple bits and pieces of the style of the widget bar, like choosing a light or dark version of it, but there's really no way to affect its behavior.
I generally advise people to skip using the widgets entirely - there's really no need to display a visit counter (why would your visitors care?), and there are usually better ways to provide album information (many skins provide good tools for this).
The ability to leave comments is problematic, for the simple reason that most web pages aren't really interactive. The visitor is supposed to look
at what's there, not alter it. That's why even sites that offer some ability for give feedback generally shunt you off to a dedicated "message page" of some sort.
There are a few skins that allow you to do something like put a button in the caption area that launches a new message in the visitor's default email client, pre-addressed to you, with the file name of the image already embedded in the message. But even that is awkward because some visitors live in webmail, and don't have a default email client configured.
I don't know what the magic answer is, but it pays to understand what you're up against.
