How to overlay an image

Hi hope someone can help this PS newbee

I am trying to over lay an image,

I have one main image and what i now want to do is have a much smaller image, that will overlay the main one and place it in the corner say of the main image, so you can see both images,

Hope this makes sense,

Thanks
Darren

Yeah...all you have to do is open both images, drag the smaller one onto the main one. Each will be on its own layer now. Make sure you have Layer 2 selected in the Layers palette, and then use the arrow tool to drag it wherever you want. If it's too big, press command-t on mac or control-t on pc to resize it. Hold down shift to maintain your current proportions. Hope this is what you were talking about!
