Link a Image to a website

Hello,

It's possible to link an image to one web site?

For exameple in the main screen I have in one corner a picture of sap logo.

It's possible to configure the image to click on it an to go to www.sap.com?

Another thing, how can I delete the pictures that I have uploaded?

For example I load 3 sap logo and I am going to choose one of them, it's possible to delete the other two?

Thanks!
