you need one Image per image file you want to load, but you can apply
the same texture/image to multiple objects.

Well, the image data need to be stored somewhere, so when you call read
a second time the original data is overwritten. Assigning an image to a
texture does not move the image data someplace else it just uses the data.

yes, that is the way to do it.
