I think it is possible to use your earnings on Dreamstime to buy photos, not sure though if it works below the $100 threshold. But if yes, you could simply find someone (for example here on the forum) with high-level images and make an arrangement that you buy a few and that person sends you the received amount (minus tax and fees likely). You don't get the full 42$ though, maybe somewhere around 15-20$ only - but it's better than nothing.
You could also wait for the 100% royalty day, as mentioned before, and do this transaction on that day and receive more.
