I have received them but can't figure out to give them. How do you post a comment with a graphic?

When you see all the graphics, many have a website link, so if you click on the graphic it will take you to the site. There on the graphic webpage, there will be a field with the HTML code to be copied, it is usually under each graphic on thier site. You copy the code.

Then on my cat space, when you click on the button to leave a meow, there should be a small title bar at the top of the meow field with HTML. Click on HTML and when that window opens, paste the code you copied from the graphic website and click on submit.
