Sometimes when sitting at a text only terminal, It would be nice to see some kind of picture even if it was crude. For example, you just got an email saying you have to look at this picture! Here you will get a chance to experiment with pictures from the command line. Thought not perfect, you may have to stand back a bit to get the full effect of the pictures. Also too, if you want to put pictures on the text only lcd signs, this is a good way to convert the pictures.
Note: the higher screen resolution you are using will improve the pictures.
Step 1: Get some software.
You will need a jpg to ascii converter, image converter, and a page grabber.
For Ubuntu based machines:
sudo apt-get install jp2a imagemagick curl wget
