A jpg image opens in Firefox but not Internet Explorer
Microsoft Internet Explorer 8.0 dropped support for jpeg images saved as CMYK (Cyan, Magenta, Yellow, and Key) and now only supports images saved in RGB (Red, Green, and Blue) mode. Below is an example and easy way to verify this issue. In the example below, we have two images; one saved in CMYK and the other saved as RGB.
| CMYK | RGB |

If this issue exists, the CMYK image appears as a red X or broken image in Internet Explorer. However, opening this page in Chrome or Firefox should show both images. If both images are visible to Internet Explorer, this is not the issue with your version of Internet Explorer.
Fixing this issue
Image editors (e.g., Adobe Photoshop, GIMP (GNU Image Manipulation Program), and others) can identify if a jpg image is a CMYK image and saving a CMYK jpg as an RGB JPG. Online services can also be used to convert any JPG image into an RGB image.
