I got a code that allows you to take an image from you computer, and turn it into a bunch of ones and ohs! The thing is that it's a PHP script.
Oh, and since it's text, if you were to say, upload a tiny image, like my avatar, it would take up the whole window.
CODE

<body>
<br />Upload the image you want to asciilize. <br />Supported image formats are: gif, jpeg or png. Max filesize is set to 50 Kb and allowed measurements are H<500 px & W<500 px.
<br />Please, there is no point in trying 2mb screengrabs and such, as it will just fail anyway.
<br />Keep in mind that the ascii version will be 6 times wider and taller = 36 times the area.
<br />As such, large images might stall or even crash your browser.
<br />The optimal image to asciilize, is one with few colors, sharp transitions, around 200x200 pixels, and large areas of the same color. <br />
<br />Upload it to any php-enabled webserver if you want to play with it. PS: If you wanted to enable larger images, you might need to re-configure your webserver with a larger POST-max-filesize, longer execution-timeout-limit.<br /><br />
