If you are going to frame a picture take this into consideration......

People buy pictures that they have an emotional attachment to.

I look around my house and I have pictures of old maps (from my area), football (We have a picture of Clemson's Death valley hanging in our den), civil war pictures, Mayberry (I have a print of barnie fife).

Now my wife has pictures of our kids, grandkid, flowers, plants, etc.....

My point being if you have someone who loves English Bulldogs, they will have pictures of the dog itself or other bulldogs.

If you're looking for resell rights look for niche photos.

Civil war, pets, nascar, tennis, etc....

Now here's something I do..... I take old photos out of magazines and frame them. I once took an old civil war calendar (1996 I think), well instead of throwing it away I took the pictures, cut them out and built frames for all 13 pics. I ending up keeping 2 of them but sold the rest for $20 bucks a piece. I've done the same with old coke ads out of time life magazines.

Now if you are bound and determined to sell what you have look for new business's opening up. That need pictures to fill their walls. Maybe flea markets... Or sell them to stock photo companies.

Hope this helps.....
