Why is the quality of those images so bad? I know I'm scaling them down quite a bit, but IE seems to handle it alright.  Chrome handles them alright, but if you zoom in/out of the page the images will pixilate.  Is there a css trick I need to do in order to maintain quality on a scaled image?

I tested in IE8, FF, Chrome and Safari. All look the same: really pixelated.

Your images are really big and asking your browser to resize them (along with all that goes into pixel reorientation when changing sizes) is a little unrealistic.

I would HIGHLY recommend resizing the images yourself and using the resized images.

Alternatively, you could use javascript to do it more accurately.

That's kind of weird that IE is showing pixelated for you.  They look fine on my end.  I tried some resizing, but it looks bad in FF.  I know that some users have a default page zoom set, so I was hoping to scale down a higher quality image, so that it wouldn't show up as a blur when zoomed in. I'll take a look at that javascript

May ask I why you are trying to resize them? Why do you need such large copies available?

Here is the screenshot of my IE.

There's really no reason to have them that big.  I will resize the ones on that page, and see if it clears it up. I'll post back in a sec.

I just resized them.  If you don't mind, will you check it out again?

So much better!

Graphics programs are intended to recalculate and compress pixels while attempting to not lose quality. Your browser is not.

Looks great. New Screenshot from FF

Good deal.  they look much more clear on the sample site I made, but on my actual test site(one which I didn't not link to) they are still messed up.  It may be a cache problem.  Thanks a lot for your help.
