Digital Photo Frame Offers

How do I print my family photos to fit into 10″X13″ frame?
I bought a bunch of 10″X13″ Photo Frames simply because they matched my furniture. I have lot of digital photos with higher resolution too, but the problem is that Snapfish, Sears, Photoworks, Target, JCPenny — all these studios never offer 10X13 digital prints..they have either 12X18 or 11X14 something…..quite a conundrum. Please suggest a way …
I cannot print 10X13 photo on 11X14 paper because I dont use a Photo printer. I use tools such as Snapfish etc which will print the photo in 11X14 format only. If you guys know a service that prints a 10X13 photo then thats the answer for my problem!
Just have 10×13 inch images printed on the 11×14 paper. You will end up with a half inch border around the print, which you can trim.
