EBay, Collectors, Flea Market & Antiques

I rarely use any of them. If I have something special to improve I use GIMP, but it's hard to learn really. There are dozens of online photo editors. Many of them free. I used IRFanview for awhile back in the day, then settled on PhotoFiltre https://photofiltre.en.softonic.com/


I've found the best is to use my cell phone and upload directly to eBay (through the computer). I can either edit it on the phone, or use eBay's lighten, crop, rotate, and background features on the fly. They didn't have those 20 years ago.

If you haven't used eBay in 20 years you're in for some surprises. Search engines don't work like they did. eBay gives the business to high price items and big sellers. Little people get little visibility. Also there are a lot of crooks. Best advice today is to cut a video of every package. In one uninterrupted motion take video of item insertion into box or bag, seal it, and apply the label you've pre-printed for the item. Because buyers lie, distort, cheat. THey claim it's broken, you shorted them, it's not as described, you shipped them a golf ball instead of a toaster. Only way to dispute crooks is with evidence. eBay will always side with the buyer without such proof.

Also put high prices on things. That gets visibility, and helps pay for returns and refunds from the crooks.

And the postage will eat you alive.
