I've seen at least one post for people wanting to create images for their games, characters and more. I LOVE https://creator.nightcafe.studio/ I have been using it for some time. The different themes, backgrounds, etc are amazing. It's just a text prompt to create what you want. You can also use an image you already have and type in some text to change it up. I highly recommend it. It's also free. You can earn credits. You can also pay and you get a lot for what you pay for. I have a LOT of credits built up, so if anyone needs any assistance with images, let me know. I usually start with NightCafe and then I take the image into photoshop and do my thing. Here's my Warlock/Assassin from my 5e game.

Hey all, I have a bunch of STL files for different characters and monsters, even some terrain I am happy to share. Some inspired by videos I've seen on DnD daily.
