You would ideally need to store the image names/numbers in a seperate table and associate the user_id with the image
So in your 'image' table you would have 3 columns:
image_id user_id image_name
1 10 1234
2 10 8096
3 5 6582
4 7 8765
5 7 6765
6 10 9876
Above you see user_id 10 has uploaded 3 images, user_id 7 has uploaded 2 images and user_id_5 has uploaded 1 image
Then you would select the images from the 'images' table based on the user_id once they have signed in:
SELECT image_name FROM images WHERE user_id = 10
So when a user signs in to upload an image you would append the 'user_id' to a hidden form field :
<input type="hidden" name="user_id" value="<php echo $userInfo['user_id']; ?>" >
Then get the user_id and the image_name once the form is submitted to store in the information in the database table 'images'
