I don't know if you think the same way, but I have found that photos are much more appealing with borders. So, with that in mind I decided to update all of my photos that were borderless. And rather than just update them, I figured that I would just delete the old version and submit a new one. Maybe that way some more people will see them...
So sorry to those of you who have already seen some of these before, and were wondering why they were showing up again.
Then again, if you think it makes a really big difference to the photo and you want people to take another look, there's no harm it deleting and re-submitting it .
I've been adding them to mine too lately.
It makes a difference.
