I am using Costco's online photo lab to print a few pictures from my digital camera for the first time and it is asking me if I want to compress the image while uploading? I am assuming this is to save file space on there servers but it seems to allude to better image quality for 4x6 prints, it says not to compress the file if you want larger than 8x10 which I do not.

Any idea's or suggestions? I just want the best image quality for the prints.
