This is always a hard question. I tried stock agencies but did not have much success. Finally, I got some of my images at a local store in Town. It is just starting but I sold more in 1 month than 2 years in a stock agency. My images sold for 75 pounds however it depends of many things;
1. Paper
2. Popularity of your image (suggest that you put it out there in an online community to test it out)
3. Mounted or not
etc...
