So maybe Clikpic is compressing your images. Until they recently increased the max size, I think 500 pixels wide was the largest size that they would host. You could try uploading one at a smaller size and see if it looks better.
Here's a link to mine on Photium (Clikpic's competitor). They recommend 600dpi longest size and optimised to 100k. I've always been pleased with the resolution.

Pics look good although to be honest I have never been fond of their templates.
