Found a great AI image generator site yesterday, Midjourney https://www.midjourney.com/
Midjourney (at least for now) will redirect you to a Discord Server https://discord.gg/midjourney where you will found a bot that produce really great AI images in less than 60sec
You just have to log in NEWCOMER ROOMS, use command /imagine and prompt something
I've made 3 images, first 2 using as prompt names of well known movies and a 3rd with the name of the AI Art & Information Community
Bot start to give you 4 variations that you can choose one to create more 4 variations or upscale
Here is the 4 variations created by Alien Apocalypse Now Joker prompt
I've picked variation 1 to create 4 more variations and after upscaled the one you can see above on first post image.
Give it a try, during the process I've seen really great and impressive images being processed, all made by a Discord bot, WOW!
