page bleed

Do you have to upload PDFs or can you just upload JPEGs? Uploading jpegs of the right dimensions is so easy when using their book maker. 8.5 x 11 becomes 8.75 x 11.25 (just add .25" to the basic book measurement and make sure everything is within the safety zone),etc... I usually overlay a grid onto my pages to make sure everything is within the safety zone. I always use the full bleed option and have never had a problem with the finished product as long as I follow their full bleed/cropping guidelines.

Here is the general cropping and bleed page for info:

This is what it says specifically about PDFs on that page:

Uploading PDF's
If you are uploading a PDF you created, beware! This method is very dicey, and full of complications. Your PDF needs to allow an extra 1/8" on each side. That is an extra 1/4" total to height and width. For example, the PDF for a 9"x7" photo book needs to be 9.25" x 7.25".

It's most important that you receive the exact book you want. We definitely don't want you disappointed if our wild and crazy printer gets a bit frisky with the trim cutter and nips the edges off your beautiful layouts.

Photo Book Size PDF Size
6x9 6.25"x9.25"
9x7 9.25"x7.25"
8.5"x11" 8.75"x11.25"
14"x11" 14.25"x11.25"

I am just a little confused. If I want my pdf file to go to the edge of
each page, how much do i have to add to book size? I am making a prom
book for an upcoming event, and want to make up a book to show from last
years prom. Thanks for any info.
