When creating images for a PC/normal Internet site, it is the compressed size of the image which affects the speed that your site downloads and displays to your users. Unlike PC/Desktop browsers, on TV Internet it is the UNCOMPRESSED size of your images that affects the performance of your site on the set-top box.

The memory taken up by the STB to display your image can be calculated by:

(width x height x 16)/8
-------------------------------	= KB (size of image)
1024 = kb

• The amount of memory used by the STB for images is related to the size of the image in pixels. It is not dependent on the content or compressibility of the image.
• Use image size tags (height & width) to reduce the amount of processing and avoid errors
• 16 is the colour bit depth the STB will display the image, at regardless of what bit depth the graphic was created at
• Developers should be aware that sites have roughly 500KB of memory per page for images (KB as result of calculation).
• Do not use full screen graphic images.
