Ok--I hope so.

Ok, I look at that. Would need to grab the Exif object then destroy the
original image to preserve RAM for working with the second image.

Ahhh! I got your other note. No, I didn't get that required 5. :shrugs:
Oppsy. And No, I haven't tried on PHP5 enabled server yet. I need to talk to

Thanks for all the help and have a great day.
