The problem: Images displaying in Firefox and other web browsers, but not in Internet Explorer 8 (IE8). This is something diagnosed as IE8 having dropped its support for JPG files saved in CMYK color mode. It’s not so common an issue as saving a JPG in CMYK color mode is a rare manner for saving JPGs; Picasa will not save in this manner, but pre press programs like Photoshop will do.

Solution: Check the color mode of the image. In Photoshop, by clicking "Image," then "Mode," you can check it. If CMYK, change it to RGB before saving it for use on the web. To avoid JPG saving in CMYK, you can also use the "Save for Web" option in Photoshop or Photoshop Elements, instead of choosing "Save As.." and choosing JPG. "Save for Web" will convert your image to RGB before saving.

So, if any of your website image is not displaying in IE8, check the image in Firefox. If it displays there, it’s likely to be in the CMYK color mode. Fix the problem by changing the color mode of the image, re saving it and then replacing in your website.
