Overlaying images #579

Hello, I would like to know if it is possible to overlay multiple templated images on the same position.

For example, I might want to insert {{image1}} and {{image2}}, one on top of the other. Image 2 is a foreground image with some transparency (or might be a smaller image), while Image 1 is a background image, so I would like to superimpose the images.

Can this be done with a template, or do I need to manipulate the images to combine them into a single image before inserting them into the template?

Thank you.
