FusionPro supports the use of transparent pixels in GIF and certain kinds of EPS files. It does not support the use of transparent pixels in PNG files.
The only EPS files that I have found that FusionPro supports are those that have been saved within Illustrator as 8 bit tiff and having the transparency option checked. I have found that the transparent pixels are not saved if you use Photoshop and save it as an EPS file. I've only been successful using Illustrator.
Please note that all files used on our system must not have any spaces in their names. Use an underscore instead of a space.
