I haven't looked at the images, but keep in mind that taking a low resolution image and stretching it to DVD size and calling it a day won't meet The Cover Project standards. Since I haven't looked at your covers, I don't know if that's the case with yours, so don't take it the wrong way.
In the sidebar on the <-left, under "Links", click "Upload a Cover". Where it says "Cover" click browse, and locate the file (saved in .jpg, and properly formatted) and press OK. Where it says "Author" type (or copy+paste) your user name. Next to country, locate the country the cover is for. For "platform", select the system the cover is for. Check "this is a raw scan" if your upload is a straight scan, final covers are NOT raw scans. If your cover is a custom cover (which all PS1 DVD covers besides the official SONY METAL GEAR SOLID covers and a few others are), then check that box.
