There are roughly 14,955,656 (14 million) unique images, giving you a 1,950,00,000,000,000 (1.95 quadrillion) chance of seeing the same image sequentially. You'll likely be the last person to ever see something if you load a unique image. The most recent image possible to pull is an image from May 10th, 2014, with the oldest being May 14th, 2008 (when they were added). You can find where a decal is stored by putting the bottom number on the machine at the end of this URL: https://create.roblox.com/store/asset/ This may give you enough of a lead to find out what game it's from if the uploader didn't put it directly in the game's name. I may or may not add more to this place. It's just a little tiny side project I put together. Send me suggestions wherever appropriate.
