Linking images to websites

Okay, i went through the memories but didnt seem to find anything to help me, i already made my first button for my LJ (this lj) which i started not too long ago to post my icons, (thats off the topic). the thing is, i want to know how to link that button to my lj -.- so when i click the button it gets me to my lj (this sounds more out of HTML than icons but i thought this is the only place i'll get some quick help).

Could anyone tell me how to do it? please?! - it will be much appreciated!
