From experience I have found that users often have problems using EPS file within FusionPro. If the EPS file has been created within Illustrator, then normally there are no issues. But, make sure that the name of the file includes no spaces. Use an underscore instead. The problems usually occur if the user has saved the EPS image within Photoshop. I suggest if you are using Photoshop you save the image as a PDF instead. PDFs are also vector based graphics.
Note that if a user is uploading a vector based graphic, EPS or PDF, to a product that the crop tool does not deploy and that the image is placed in the graphic frame on a best fit basis.
