That's what I said. Don't sign up for every sponsor that catches your eye. Scattering your meager traffic among a large number of sponsors generally results in either no sales or failure to meet the minimum payout for a sponsor.
Pick 3-4 CAREFULLY based on your personal tastes (it's easier to sell what you like). Pick sponsors like
TrafficCashGold which have sites in a variety of niches; some TGP's (and presumably linklists) allow you to submit only one gallery per day, but some will allow you to submit several galleries in a day provided they are not in the same niche.
Once you're making at least one sale a day at each sponsor (or if you find that one is converting very poorly) add another sponsor.
Concentrate on the niches that convert well for you, of course. Repeat until wealthy.
Exception: If you REALLY like a particular niche, choose ONE sponsor that specializes in that niche; then choose two or three more sponsors with a variety of sites.
