Graphic web advertisment

hi all i am looking to design an advertisment for my website just so i can place it on one of my other websites i was wondering how i would be able to do this thanks

I think you need to give some more information, as it’s not really clear what you mean. You could create an image with a link.

Most likely an ‘absolute URL’ to the image in question is probably what you are after; I assume this ‘image’ is hosted upon just one server but you want it displaying on your other websites. Without having to upload several copies of this specific image to each one.
