If you want to upload pics and make them look nice here I can try to help you out! Instead of using paint to re-size your photos, use the website that uploads your photos to do that!
First you have to sign up at photobucket and create your own account.
www.photobucket.com
After that, you can upload photos to your account. Before clicking "upload images" first check out what settings it's on.
Click "more options" below the big "upload images" button. You'll see a list of dimensions to upload them as.
Depending on what you like to upload them at. But anything bigger than 17" screen is way too big.
I upload mine on the 17" option, to give you an example click
hereAnyway, after you have uploaded your image, you will see several different links beneath it. Use the one that says IMG code to post it here.

So yes, just do that for each different photo, and you are done!
Also, in the photo forum you can post up to 10 images per post!
Enjoy! Hope this is what you meant...
