I need a little guidance on saving pictures for submitting to Challenges. I shoot in RAW, edit in Photoshop, and save in JPEG on highest quality. Then I used Image Size to set the dimension pixels to 640 so it seems as if I should have a really high quality image but when I uploaded to the Challenge, it was bit-mappy. What am I doing wrong? Thanks for your help!

Resize it before ever saving to JPEG. Only save it to JPEG once, at the very end. That will help avoid compression artifacts.

Rememeber to save your original just in case you are asked to submit it for a DQ inquiry.

Use "Save for Web" and size longest side to 640 pixels and try to download again. It should make a big difference.

I believe that the Photoshop 8 will have RAW capabilities. I believe there's a RAW plug-in for Photoshop 7 on the MAC.

correct me if I am wrong, but I believe you'll get slightly better results if you crop more and resize less.

Also, as a matter of workflow for those wishing to enhance their skills, it's best to convert all RAW files to a lossless format (I use PSD, some may choose TIF) and always work with those files. When you need a JPEG use Save A Copy or use Save For Web.
Also, name your ouput files carefully.

Not that you (or anyone here does), but you should never save as JPEG, close the JPEG, open it, modify it, then save as JPEG again. No workflow process should ever start with opening a JPEG.

Don't you find it annoying and stupid that there's been a file-format choice called "RAW" since (at least) Photoshop version 2.0? (BTW: you can get interesting "effects" if you open various types of files with the Raw format selected; try it with a spreadsheet or sound file.)

If I don't really care about superior quality and am in a real hurry I will sometimes open a JPEG and resize it for a thumbnail or email insert and resave to another JPEG.

But otherwise ALWAYS do your editing in a lossless format (TIFF, Photoshop, or your program's "native" format) -- never re-save a JPEG once it's been opened.
