Facebook and Instagram are creating hidden ASCII art of your photos

Zuck-art-3

If you've ever uploaded a photo to Facebook or Instagram, chances are there are secret ASCII renderings of them out there, if you know where to look.

Facebook has been creating ASCII art — that is, recreating your images out of text characters — out of your photos and anyone can find it. The feature was first spotted by Twitter user Mathias Bynens and has been confirmed by Mashable and others.

The photo above, taken from Mark Zuckerberg's Instagram account, shows the original version of the image he posted with Instagram cofounder Kevin Systrom and the hidden ASCII version.

As Bynens points out, you can find the alternative images by adding ".html" or ".txt" to the end of an image's URL. The former creates a color image while the latter creates a black-and-white one. Actually grabbing the image, however, is not quite as straightforward as simply pulling up a photo on Instagram or Facebook's website.

First, you need to get the URL for the image itself, not the link to the post that accompanies it. On Facebook, you can do this by right-clicking on an image and selecting "open image in new tab" or "copy image URL." Once you've opened the URL in a new tab, look for the ".jpg" extension. If .jpg appears at the end of the URL, then you simply need to add .html or .txt to get the ASCII versions.

On Facebook, the trick works only for publicly shared photos, and it won't work if there are extra characters after ".jpg" in the URL, even if you delete them. It's not clear exactly why this works with some images and not others, but you may be able to make it work after a bit of experimenting.

For Instagram, the process is a bit more reliable, if more complicated. You'll need to open the source code in an image, which you can do by right clicking and selecting "view page source," in order to find the image's URL. Once you've opened the page source, the easiest way to find the URL is by searching the web page (CTRL + F) for ".jpg." Then, copy and paste the URL into your browser and add the .html or .txt extensions.

The process is a bit involved and it's still not clear why Facebook would have this as a "hidden feature," but it's definitely one of our favorite Facebook Easter eggs to date.
