In editors/js/markitup.js

.css({ backgroundImage: 'url(' + settings.root + 'sets/default/images/' + button + '.png' + ')' })

I found "button" this variable is presented by number

but real picture file name is like "bold.png"

so problem is mismatch file name

This is the third time this has been reported hehe.
This issue has been fixed in -dev and the solution will be included in the next release.
See #394068: markItUp: icons are no more visible.
