You could use an iPad with procreate to look at all of that.Or even the combination of procreate and Affinity designer. Both are cheap and will give you all the viewing capabilities you need.Affinity Designer for desktop is also a great alternative to the adobe products.
I thought he was trying to have Sales people preview art (misc file types) sent in from potential customers to check the quality of their submissions, not generate art (or file) to go out. But maybe I'm wrong, lol.In reading on Mystic Thumbs ($29.95), it looks like it can open any (?) file type and create a thumbnail size file for distribution. Do I have that right?
