Hi. I have two images, one taken by a thermal camera and the other taken by a digital camera. The two images have a different spatial resolution. I would overlap them. How can I do?

If they have the same aspect ratio, you can simply adjust the size with imresize(). If the aspect ratio differs, then you'll have to pad or crop accordingly (using imcrop() and padarray()) to enforce colocation of image content.
How you do the overlay depends entirely on what you want. It may suffice to merely take the average (or a weighted average) of the two images.
