Both

Like I said, I like the way the connect now widget it does. It has 5 built in icons and sixth custom, where you can select two files (one for disabled, and one for enabled connection)

If needed I can provide screenshots of the ConnectNow widget, however seeing/feeling it yourself might explain a lot more I can understand you don't want to install extra widgets.

The way I would like to see in Profile Changer Widget is 2 options(or maybe 3):
(0.) - Default the way it's now
1. - Follow theme
2. - Specify custom images by means of a file selection window/popup
