Deleting images?

I can’t find how to delete an image in Blender. That’s really weird, cause it seems like a very basic thing.
I thought “X” deletes it, but it only disconnects it.

Hold SHIFT and then click the cross to permenantly delete. But you still have to save, close the .blend file and reopen for it to be gone. This last part could really be improved.

There could be just a button to delete the image… this is ridiculous.

In the past I’ve heard that the concept is to keep the image available even if you want it deleted, just in case you change your mind and need it back. I agree with you, but maybe two options then, one to unlink and other to permanently delete straight away.
