I have a portfolio roughly the same size as yours... in the first two years I made around $1300, and in the last 12 months I've made about $3000. If you look around, there are some contributors with relatively small portfolios and an even larger amount of revenue over the same time period. I guess what it comes down to is having high quality and niche images along with a range of other things like the right keywording, color editing and so forth.As for making more money having your portfolio spread among other agencies as well, theres really only one way to find out. I've been extremely satisfied with the search placement for my exclusive images here on DT and wouldn't give that up for anything, especially since some of my highest selling images are for very prominent keywords and I'd lose that placement if I didn't have exclusivity. posted in $$
