Scale images when resizing screen

Hello all!

I am currently working on a prototype of a site where I want to be able to click a button to display a gift, then click the gift to hide it again, this part I have working.
I am however having problems with scaling. My main big image of a room scales just fine, but the smaller images that are the gifts do not scale at all. I am a bit new to this type of design and was hoping to find some help here!
Thanks in advance for any help!
