I have an old program from 2002 that worked with Mac OS X 10.5 and earlier called Thumbnailer v1.1. I have newer computers that will only run Mac OS X 10.7.x and higher, so I can no longer run that version of Thumbnailer and I don't know where to get an updated version. I have done the usual types of Google searches to no avail. So, I am wondering is there another program with the same feature that will work on Mac OS X 10.7.x and later?

Any help would be greatly appreciated :)
