It doesn't look that trivial to me. Dreamstime use several scripts to enable the flash browser and because you cannot access area in Blogspot, there is no straightforward way to incorporate those into your blog. I tested that just copy-pasting flash browser link wouldn't help. Unless DT gives some tool to incorporate it, I don't see any other means to use it in external websites.
Hey thanks for bringing that to my attention. Its completely useless to put that blog in profile. Now I changed it to more logical blog. I also contribute to a photoblog http://photokatta.blogspot.com/.
