If it's not featured quickly it's rejected. They just don't SAY Rejected--they leave it permanently as submitted.
You might want to just recreate it and resubmit it. If it's a popular template, definitely recreate it. If it's a rarely used template or an image you submitted, save the template image and upload it as a new image. Then put the same text but as small as possible (I know you can do 1 pt and I think you can even do 0 pts) and in a color that matches the IMAGE, so it will be invisible (e.g., put 1pt black text on a black part of the image). The IMAGE DESCRIPTION is whatever text you add. So if you JUST upload your previous image, the IMAGE DESCRIPTION will be empty or something else.
