Comment 24 for bug 986534

Regarding #22, my personal preference would be to keep/update checkbox_light.png, remove checkbox_light_new.png and update the code to point to the former file.

First of all, I find marking files with _new to indicate they are newer a bit silly (especially considering we have version control). Both because it won't be new a couple of years down the road, and it also encourage people to add file_new2 or file_new_new which makes it harder to keep track of what they do.

PS. I filed bug 990623 for the code part of change-image-on-hover.
