Look through an image

Several times, by accident, I’ve ended up looking “through” a 2D image in the 3D view. This is very useful, but I can’t figure out how to make it happen on command!

Hi Aaron Curtis

Move the image to 2D view by pressing CTRL,
When have it in 2D view move the image again from 2D view to 3D view with pressed CTRL and it will look trough the image…

Great! So hold CTRL and drag between cells. Another brilliant but kind of hidden feature!
