Still trying to figure this out!

Okay, I have seen a lot of things on other blogs that I would love to add to mine, but have NO idea how. Like the Hypoplastic Left Heart Links and pics.........I have seen things at the AHA website that I would like to download here too. HOW DO I DO THIS? HAHA No I am not a TOTAL computer idiot, however I have NO idea about this blogging thing. I did find a new background that I love....but I would like to add other things as well. Please email me at kcole882020@yahoo.com if you have any info for me! THANKS!
