Blurry Pictures?

I noticed that some of the pictures that I uploaded to my (and my clients') blogs looked kind of blurry! This was especially so when the images were photographs of some kind. It also happens with 3D-related images as well.

At the beginning I was uploading images using the .jpg format but I found that the .png format made the images appear a lot clearer! So this is something that you may want to try when uploading images.
