I have two photos I would like to upload to DPCPrints to sell.

I have taken them in RGB mode a few years back and worked them in Lightroom recently, then moved to PSCS2 for final editing. In doing so, I believe I converted them to Adobe sRGB.

Now I can't convert my PSD to JPG, because there is no JPG option. There are only a few format options, among which PNG and TIF.

I believe DPCPrints takes only JPG. What can I do?

Sounds like you have the image in 16 bit mode. Convert it to 8 bit mode and JPEG should be an option again.

The profile is another matter - make sure you convert the image to sRGB before saving.

(edit to add)
If you want to retain the full 16 bit image then be careful not to save the 8 bit version over it. If in doubt, duplicate the image in photoshop and use the duplicate when converting the image depth and profile before saving it as a JPG.

Someone may know if "Save for web and devices" will do all this for you. I've always used the old-fashioned, manual way...

It may also keep you from saving it as a JPG if you have layers. Try flattening it first.

alanfreed: I usually have layers and it doesn't keep me from converting to JPG, so I guess this is not what causes the problem.

MilesW and Dirt_Diver: I will try the 8-bit thing as soon as I have time and get back to you :)
