Gabriel, I already tried In ower list in Argentina... I reveived a lot of answers of people who wants to help me, but we can't find the solution to my problem, because of that I'm asking here. Anyway, thank's to try to aproach me to ower community in PyAr. Ah, the thread is "Guardar y recuperar imagen desde Postgres". That was my first problem, and then it become to the one that I'm trying to solve now.
Thanks a lot, Marcos Alcazar -- http://mail.python.org/mailman/listinfo/python-list
