Wal-Mart's self service photo processing OWNZ ME! HELP!

I'm pretty new to all of this and I could really use a little expertise please! Here's the situation... I have a Cannon G5 and I took a picture of my neighbors at my camera's maximum resolution (non-RAW) of 2592X1944. Now I can pop out my smart media card with that pic on it, run over to Wal-Mart, and use their Kodak photo station which will let me make 8X10 prints of the original photo all day long. Problem is there are some flash reflections on the reading glasses in the original photo. If I open the original picture in photoshop and clean up these reflections, then save the picture at the original resolution of 2592X1944 @5M pixels, I can no longer make an 8X10 on the machine? It will only let me make 4X6's!? Why is this? I really would like to make an 8X10 of this picture only without the relections in the subjects glasses... Please, someone tell me what I'm doing wrong....

Thanks in Advance!

Send me your file (corrected) jslessardATifrance.com . I'll help you the best I can.

It's possible, that if you are saving the corrected file as a jpeg, that PS is set to compress the image so much that the Kodak system isn't "seeing" enough data to make an 8X10. I had this problem with the Epson PictureMate. I had just loaded PaintShop Pro and the default jpeg compression was 20%--my 6 MB raw files were converted to 750K (yes, K) jpeg files. The printer didn't know what to do with them and just spit out blank pieces of paper. I reconverted and saved with 1% compression and it worked fine.

Good luck!
