Hey Kathy, I'll warn you upfront - I'm not the most technological person here, so this may not make sense LOL
First you need to upload your pics from your computer into a photo sharing website like Photobucket or flickr - I use photobucket because I can't work out how to use flickr LOL
Then, in the picture sharing website, each photo you upload will be assigned a weblink and you just cut and paste that link here into the message, we click on it and are taken to your pic.
Does that make sense at all?
