For me, Image Handler 4 doesn't work with a site that's already populated. I would not recommend installing it unless it's a fresh Zen Cart install.

I have backups of the site that would give me the white screen on IH4 when I tried to merge it, in case anyone ever sees this and wants to respond. It would be nice to see what I missed.
I install Image Handler almost on a weekly basis for new an d existing shops, and never got a white screen. It must be some other module, which needs to be merged in to the new files.
