Well, this tool is meant to make it easy to turn bbcode color coded text into 256 color escape character colored text that can be rendered by bash. I made this to turn ascii art into something I can use with my terminal windows for bash login messages.
My prefered site to make an image into an ascii art is https://my.asciiart.club/. This is because they support transparency and allow export into bbcode. This script lets bbcode ascii art usable in terminal environments.
