Problem with images and Chrome, Firefox, IE

I have a Joomla website and I observe a problem with some images.

In Chrome images look really good and sha开发者_JS百科rp but in Firefox and IE the images are not that sharp and the colors are a bit strange.

Take a look at the photos below. The difference is more obvious on the Standings were the emblems of the teams are really small.

Any suggestions??

You're telling the browser to scale the image from 150 pixels to 60 pixels.
Most browsers aren't good at that.

You should create images that are exactly the right size using an image editor.
This will give you complete control over how the image is scaled (image editors do a much better job than Firefox), and make the files smaller too.
