Serbia has grown very protective of the information about its orphans in the last few years, due to several scandals involving corrupt adoption facilitators and agencies. Therefore, there are no photolistings available of Serbian orphans. This does NOT mean that those orphans do not exist, or that they are receiving adequate care in their own country! There is progress being made, certainly, as some orphans are moved out of institutions and into foster homes. But many, many more wait. At the same time, the removal of the corrupt intermediaries has meant that the costs of a Serbian adoption are far lower than other Eastern European countries.
Here is one family in the middle of an adoption in Serbia. Having requested a child aged 2-4 years old with Down syndrome, they received the files of 4 children. Of these, they have chosen one. We do not have names or faces for the others, but they are there. How many older children wait, as well? How many with other conditions? They are no less real than the Russian, Ukrainian, or Bulgarian children profiled on Reece's Rainbow. Or the Asian, African or Latin American children, for that matter!
If you are interested in learning more about what's involved, you can check out this site. This is not an agency -- Serbia has not authorized any agencies to operate under the new laws -- just a private site for sharing information by people who have been there.
