Recently we ran into a problem where we had uploaded some images and they were using CMYK – which will not work on some browsers and can result in images not being shown or displaying as broken. To avoid this you can easily save your images in a format that is more ideal for the web (RGB). To do this in Photoshop (CS4 shown, it’s similar for other versions) just do the following: 1. Open your original file, adjust according to your needs. 2. When ready, click File -> Save for Web and Devices 3. When that comes up, make sure the checkbox to convert to sRGB is checked and it is in the format you desire (small note: PNG files will not work properly in IE6). 4. Click Save! You now have an image that will work properly!
