Agnes, I fixed the pictures in your post for you.
If you have other LOLCats you want to post, you can do either of these things - just right click on the picture, click on properties, copy the address and then post that with img in brackets at the front and /img in brackets at the back. Or if it's a picture you want to save, right click on it, save the picture, then go to a photo sharing site like photobucket and upload it there. They will give you the IMG code that you need to post it on the DIS.
I'm sure that was clear as mud.
