Ignoring most of your comments here and assuming you actually want help, the basic idea is:
1. Scan the card using your scanner's application (NOT a camera or cell phone camera/app). Just the card, not inside a sleeve or toploader. Line the card up as straight as possible on the scanner glass
2. Using a free image-editing app such as Photoscape, properly crop your card and make small rotation adjustments if it's crooked
3. Upload the images on the card's page
4. Until you've provided a sufficient number of accepted images, wait for them to be accepted or tagged for replacement if they have issues
To make sure your cards get accepted, don't submit photos. I'll repeat, DON'T SUBMIT PHOTOs. For some reason despite the rules being clear, members will take pictures of cards on display stands, in their hands, on a table, etc. If there are obvious signs of photography (flash reflections, glare, skewed dimensions, imbalanced colors), the images will be tagged for removal. If they're swiped from a site like COMC where they're watermarked, the images will be outright rejected.
Beyond that, if you have any questions, please post them here and one of this site's many helpful members will do what they can to assist you.
