if there's a way that makes reblogging my pictures beneficial to me
The fact you release your work is beneficial, raises your reputation as a designer, photographer or whatever you specialize on. But you need to have a plan how to better promote it.
You deploy copy protection measures only if you don't want others to use your images.
You release your images with a license for others to use, that promotes your business if others find them useful because they will surely want custom images to be developed and trust your expertise. In this case using a copyleft license you could promote your name quite fast. The drawback is you will have to invest time and effort without direct compensation although you could politely have a statement for sponsorship.
If you publish your work you aren't so concerned about reciprocal links. Because you will be an authority site for your work. And the relevant repositories you would publish your work have high enough ranking to keep you as the leading entity over your work.
