What size you upload can certainly be an issue. If you upload bigger than recommended it will look blurry. It will also be clickable (notice the hand over the image when you have your mouse hovering over it). Try clicking it and see if it gets less blurry then.

Other than that, I think that you might want to try some sharpening after you downsize to 700 pixels at 72 dpi. Try the Filter->Sharpen->Unsharp Mask. My default settings for sharpening web files are: Amount 117%, Radius 0.3, Threshold 15. This might be too sharp though.

Photoshop guru Scott Kelby uses Amount 200%, Radius 0.3, Threshold 0 for sharpening photos for web, this is even more sharpening than my settings. Try them both and see what you think. The threshold works the opposite of what you think. Low threshold means lots of sharpening. The amount and radius are more logical. High amount -> lots of sharpening. Radius: Don't go higher than 2, and lot less on web sharpen. Threshold below 3 could give you noise.

Ops, didn't see that you're on PSP... Sorry. I'll let the post be, in case others wonder too.

Googled the issue: In PSP, you should have an "Image-Resize" option. Try it, and see if you can manipulate the ppi to 72 and your file size to 700x700 pixels.
