Put someone/something in a glass
This is an easy activity to do.

The results are:

There are just a few steps:

1/. Find a suitable image to "put in the glass".
2/. Find a suitable glass, at least 1300px high.
3/. Remove the background. That is copy the image to a new file, transparent background.
4/. Save the "in the glass image" as a Compuserve GIF, (which will have a clear background).
5/. Using the Edit/Free Transformtool, size in the image to the glass.
6/. Save the image as glass_final, as a .JPG and you are done! A nice easy fun task!
