Which picture file formats are supported by Quark Promote?
You can add PNG, TIFF, and JPEG picture files. For best results, pictures should be in CMYK mode and have a resolution of 175 dpi. (To find out the resolution of an image, see the answer to “How do I find the DPI resolution of an image?” in this FAQ.) If you use an image that is less than 175 dpi, a warning icon will display on the picture in the print preview under the Buy Prints tab within Quark Promote.
