How to delete unwanted images/uv maps?

Hi
So my blend file has a bunch of different uv map sizes which is causing clutter as i only want to use the one size how can i delete unwanted uv map images from a blend file

You can Shift click on X in UVeditor image selector for images you do not need, then Save and Open blend file. Re opening will clear unused datablocks including images - Open is important. If you had extra UV maps - delete them on Object Data tab (triangle icon) using minus icon.

OK thx i tried the shift-x thing before and it didn’t work but just tried it again and now it does must have done something wrong before. Thx sorted now
