If anyone could offer any insight to this I would be so grateful.
I finished making a wedding album using a template for WHCC press printed books today. I've printed books through WHCC before and have never had any problems. When I went to order the book (which I created using a template) in ROES the page spreads are coming up all pixelated. The files are 300 DPI, saved in JPEG, and the average file size is about 5 MB.
