An image generator app creates pictures from a written description, called a prompt, using a text-to-image model.
In plain words
Hugging Face's guide uses diffusion models, which start from random noise and remove it step by step, steered by your prompt, until an image appears. Apps usually expose a few settings: image size, a negative prompt listing things to avoid, and a guidance setting that controls how closely the picture follows your words. Too much guidance can cause visual glitches. Libraries such as Hugging Face Diffusers let you build this in a few lines.
A quick example
Hugging Face's docs use a prompt describing an astronaut in a jungle with a cold, muted colour palette. Running it through a text-to-image pipeline returns a matching picture, and a higher guidance value makes the result stick more closely to that description.
