Download 'Stylish', there should be a little 'S' symbol in the bottom left corner of your browser.  Click on that and choose: write new style > for this URL.   Then it opens a window with some code in it.  Just delete everything in there and paste the code below.  Then enable the style.

@namespace url(http://www.w3.org/1999/xhtml);

@-moz-document domain("pixeljoint.com") {

/*Main Styles*/

img { image-rendering: -moz-crisp-edges; }

}

This works with mozilla and gecko-based browsers, but not with Chrome and webkit-based browsers, but it seems they found a way to solve this HERE: by using image-rendering: -webkit-optimize-contrast.

So if you are using the dev version of Chrome (14.0.825.0 dev) the code should be:

img {

  image-rendering: -webkit-optimize-contrast !important;

}

Apply to URLs on the domain pixeljoint.com

It seems to work on another computers using chrome (a mac) but for some reason not with PC (w7)  Maybe wait for next release ?
