Resource Forks

in macOS edited January 2014
What information is stored in the resource fork of digital images, ie JPG files?

I am stripping out the resource fork for some copies of my digital photos so that I can burn a CD that will play on my DVR. I've opened the digital photos(with the resource forks removed) with a number of applications such as Preview and Graphic Converter and I don't see any difference. Would photo printing be affected if I tried to print a digital photo with the resource fork removed.

What exactly are resource forks there for and what info is stored there?

Thanks in advance,

    I am not aware of a modern image format that stores anything required in the resource fork. The last one I know did that was PICT.
