I use pinterest a lot, it’s where I get 95% of my photos for edits, but I also follow a few aesthetic/art blogs that have good content for stuff. On pinterest if you can search [character name] aesthetic/fan cast and loads of photos come up

Personally I keep to royalty free photos and if I’m unsure of a photo I’ll try and do a reverse image search on google but l 99.9% of the time pinterest photos are royalty free so don’t worry about that. I never go on photography sites, too much risk tbh, can’t deal with that drama !! Avoid photos that aren’t royalty free at all costs !!!! Can’t risk getting a sued over an edit abt a fictional character lmao

Good luck editing !!
