Sean:
The images are of various computer hardware. As far as translation, not all vendors can handle PNGs and TIFFs, or PSDs. According to what I have researched online to date, some can, some cannot. The problem seems to be in planning for SOME of the Asian translations, as most Western and Eastern European can handle PNGs, PSDs, and TIFFs. I am planning for the future here and developing a workflow, so figured now was a perfect time to ask. Want to make sure I am using the most widely used format, and it appears JPG is. Some of these clients will be editing these images to customize the documentation.
