I know, I've been doing that but sometimes the pictures rendered are from lower quality images (Jeanne D'arc for example, the anime/game art or similiar art to it). So I end up cutting it myself.Im going to do the same.
Altough i like to have not too much potraits and profile pic's. To be exct i always go with 2-3 profile pics and 1 potrait.
Also. u don't have to necessarily cut it out yourself. Googling helps a lot with this one.
The best keywords are: "(girls name) render", "(girls name) png".
There are quite a few anime-render sites which specify in only transparent pics, it really comes in handy.
I always have quite a lot of portraits and profiles though. For example Jeanne D'Arc girlpack has 31 portraits (transparent background). Which I cut 27 of them. (11 normal, 15 happy/sad/libido, 2 naked... still need to add naked portraits).
And profiles? 74 of them lol. None of them are bad enough for me to get rid of them too... (I always cut my profile pictures to 1125x1545 - meaning I crop them to the size and sometimes make them less shiny or add parts that are missing in the pictures. So you could say I edit the profiles.)
Hmm maybe I'm overdoing it?
