I'm having a bit of a problem and was wondering if you have encountered this issue before. On my layout I have graphic files (JPEGs) I've added to the layout. When I export to PDF, the graphics are dropped from the PDF file that is created (that part of the layout is just blank). When I tried to go around this problem by creating TIFF files instead of PDFs the background image exported but was of very poor pixel quality. When i increased the pixel quality then re-exported the files the background image was blank again. Do you have any suggestions on how to fix this problem?
