Sending pictures via email - Resizing?

We have sent 4 photos to a relative and they have complained that we should have re-sized them first!
Does this mean that after selecting each photograph, I should right-click and send to compressed file?

I have looked in Windows Explorer, My Pictures, selected the photo and tried to re-size it here but do not see the option?

I am using Windows XP, 40 GB h/d and 1024 ram.

I am hoping that someone can point out where I am going wrong?

Thanks

Thanks very much for the tip

 

I offered microsoft's way, as I needed to do the same and found it worked well for me. I tend to save as many links to programs, and help pages, as I can- impossible for me to remember them all - Snapfish ia also useful, and I use it occasionally.
