RE: Trying to Make extra $$ with my Wife's photos. Any ideas?

Ebay.

Not for the photos but for your stuff. A few years back I wanted needed to clear out a bunch of stuff that I just didn't use or need and over the course of a year or so sold a ton of stuff on ebay.

I learned there is a right way, and many wrong ways to sell on ebay ;)
Biggest investment is time. It takes some time to photograph, research value, make an ad, and package items up correctly for sale, but once you get in that groove, as I did, it's not too difficult.

Message me on discord if you want to chat about it.
