Although Textastic is primarily a text editor, I think it is also the best terminal emulator for iOS and iPadOS. I often use Textastic to SSH into a Linux machine, and much of my work involves making image files. Ideally, I would be able to run a command like imcat on the Linux machine that would display an image in the Textastic terminal. I believe this would be possible in principle using the Terminal Graphics Protocol.
