How do I give buttons simple images?

I could perhaps use CSS, thats annoying, I just want to append a sprite image as the buttons face. Anyway to do it? Could the CSS sheet load an image from my game folder? or no?

How do we do this? Seems like a important feature, how have all of you been making UI? Just sprites?

you can try:

Files----> Import files

but..Yes..I think most people use custom sprites for UI...

Have you tried to create a sprite and set an event that says "on click on sprite X"?

Thats what I had to do, create a sprite "class" as a "button" class basically. Thanks.
