I uploaded a pic for printing & the picture does not show. I just get a box with an red x on the top left. I tried to reload it several times & still the same thing. What am I doing wrong here?

Where did you upload it to, and how big is it?

Why would you come to DPC to print the photo when its on your hard drive? The link works fine for me, and I could print it if I wished.

BTW, I gave it a 9, I really liked it. Good luck.

thanks riggs. the quality is much better at dpc prints than on my beat lexmark printer. I guess the pic is just not showing up on my screen. will go ahead and get prints. oh, their cheap as well!
Thanks again!

OK -- a few problems.
1) Put it in/go back to RGB mode - the Frontier photo printers are native RGB (or a variant) based, not CMYK.
2) Upload to your portfolio a small "placeholder" version of the image, similar to a DPC entry (or smaller!).
3) Go to that photo's page in your portfolio, where you'd edit the info about the picture; WAY at the bottom is a link to "Upload a Printable File." click on that, and the rest should be straightforward.

The print files don't go in your portfolio itself, or no one would have room for more than 5 pictures or so. The placeholder images can be tiny -- they just need to be big enough that you know what they're linked to (unless you want post them in the forums or something).

Correct, if you are sending it to DPC Prints or any other true photo imaging service. The imagers use RGB.

The only time you need CMYK is for offset printing or maybe certain inkjets, where the image is being created by combinations of CMYK inks.

DPC prints are made by exposing ordinary photo paper to your image with lasers. But it's similar to imagining using one of those great computer presentation projectors as an enlarger; you'd be projecting an RGB image onto the paper. If your file was in CMYK mode, it would have to be converted back by the monitor/display device.

Besides, CMYK is a poor compromise ... it is capable of rendering approximately 7000 distinguishable colors, as compared to the 16.7 million (possible but not always distinguishable) colors available under 8-bit RGB. The average human eye can actually distinguish something like 20,000 colors, so at best CMYK cuts the useable gamut by 2/3; it's really worse though, as there are huge chunks of the color gamut which can't be rendered in even a close approximation in CMYK mode.
