Hide image information

I’m using responsive child theme. Just before Xmas were invited to upgrade. The old version if you clicked on a photo, you just got the full size version of the photo.. Now, it gives you a chance to write a bit about the picture which is good. BUT it also displays image information – what camera was used, focal length etc, and when it was posted and by whom. I’ve watched people using this and they just click straight back out again, not scrolling down to read about the photo, which is displayed further down the page under the picture.

here’s an example

Anyone know how I can disable all the junk but leave the description?
