What is catimg?

Catimg is a small utility that lets you display images right inside your terminal. Instead of opening a separate image viewer, you can run a quick command and see JPEG, PNG, or GIF files rendered directly in your text-based interface. The tool works by translating the pixels of an image into colored text characters. It uses Unicode characters to squeeze out higher resolution, effectively drawing the image using your terminal's text and color capabilities. You can also adjust the output resolution manually if the default doesn't look quite right. There is also an older script-based version of the tool that uses a separate program called ImageMagick to process the images, but the main C version is built to be much faster and has no external dependencies. This would appeal to developers or system administrators who spend a lot of time working in the terminal and want a quick way to preview an image without breaking their workflow. For example, if you are browsing a folder of downloaded photos or assets over a command-line connection, you can quickly check what a file looks like without launching a full graphical application. One notable tradeoff the project highlights is between speed and color accuracy. The older script version is much slower because it relies on ImageMagick, but it produces noticeably better colors. The standard C version prioritizes speed so you get near-instant results, but the colors might not be a perfect match to the original image.
