If you have images of higher quality/resolution, just upload them over the same images of lower quality/resolution. Go to the file that we already have, click "File History", click "Upload a new version of this file", choose your file, click "Upload file", and that's it.

Once you upload your images, you can put them in the gallery, no problem.
