Make a new blog, upload the pictures and put the affiliate link in the caption with some sexy call to action (clickthrough link and the source link should be your new blog url). Use dating offers, I use pay per sale, but you can use pay per email or something like that (as people already mentioned, crakrevenue is good). Also, use link shorteners. From my experience, working with adult tumblr blogs for the last 2 years, having a web site is not much of a benefit compared to directly posting shortened aff links - they ban both just the same.
Use different Ip or VPN for your new blog, as well as different user agent (download the plugin called random agent spoofer for that) - you want to make it look like as the two blogs have nothing to do with each other.
Then reblog to the queue of your big blog pics from your new blog. Post 50 per day. There is no guarantee that you won't get banned, but I'm pretty confident that enough time will pass until they catch you for you to earn some money and develop new blogs, so even when they ban you it won't be such a tragedy.
p.s. A tip - it's better to have 4 blogs with 5K followers, than one with 20K. Thats just my opinion based on my experience.
