No problem, first you have to upload the pictures to somewhere. So if you have like a personal web page or like a Geocities web page you can put the pictures on there. Then you just need to put a link that shows the image. Now if you are using the Live Journal program on your computer you just need to click on EDIT - MAKE LINK/IMAGE and then just put the location of the image you want added to your journal. Type the address in the internet address portion and then make sure you click on the dot that says Image. So if the link to my image was http://home.socal.rr.com/nad/images/test.jpg
then I would put that in the internet address portion.
Let me know if that helps!
