JPEG (.jpg) images are supposed to display effortlessly in all web browsers without issue, right? WRONG. In the last 3 months, we’ve had half a dozen calls to our help desk about images mysteriously not showing up and they all were the same root cause: the images were saved in the incorrect color format. There are other causes for images not displaying, but this seems to be rather prevalent.
JPEG images can be saved as CMYK or RGB format.
- RGB format (Red, Green, Blue) is a light-based additive color model designed explicitly for color display on electronic systems (i.e., screens)
- CMYK (Cyan, Magenta, Yellow, Black) is a print format, for 4-color process printing. Most browsers understand this format BUT NOT ALL OF THEM. Internet Explorer 8, for example, does not.
While incredibly hard to troubleshoot, the fix is relatively easy: simply change the color format. There are lots of posts about how to do this, including this nice one from PLAVEB, and there are even some free converters out on the internet (though I haven’t used one of these, myself). Fortunately, the issue seems resolved in the newer browsers, but it will be a while before we can forget about it completely.
Have you run into any image issues?
