Please use descriptive image names
Regarding your latest uploads, please use more descriptive filenames than just the the generic screenshot name.
A descriptive file name and a good description will make the image much easier to find later.
You can move the images (renaming them) by clicking the More tab and then Move. You might get away with not leaving a redirect since they are quite newly uploaded and there is no other pages linking to them, but usually you should leave a redirect (also external sites might link to them if they have been on the wiki quite some time).
