“A bochur is permitted to request a woman’s photo, but a woman shouldn’t
be doing so because men weren’t created for beauty but women were”
This sounds off to me (and certainly, such a statement could not be found
in pre-modern sources). The problem is, the Gemara does forbid a man to
betroth a woman unless he has seen her, but not a woman. One could
argue, though, that if the man has seen the woman, she has presumably
seen him as well.
(In any case, rabbonim have spoken out against asking for pictures.)
