Viewing jpg pictures

New W10.
In W7 I would simply click on a picture to enlarge it. Some of mine are cartoon drawings with the punch line or caption running along the bottom. Just one left click was needed to view the whole thing.
Can such a simple procedure be found in W10?

When I click on a picture in W10 I get a black bar running along part of the bottom, which obliterates the caption. The bar carries two arrows, a waste bin and something that I can't identify.
Can this intruding bar be moved away?

Start/photos comes up with a variety of photos selected at random. My pictures are not in albums but are spread in various files all over Documents.What use might I have for this 'Photos'?
Thanks

Yes. Windows 10 still includes the Photo Viewer that you are familiar with from Windows 7.
Restore Windows Photo Viewer in Windows 10

Thanks, just what I needed
