Fuskr Autor: Dan Atkinson

Transform single image URLs into stunning galleries with intelligent pattern recognition!

Ever landed on a single photo and suspected there are more just like it? Fuskr finds them for you. When an image URL contains a number — like example.com/photos/08.jpg — Fuskr works out that there are probably images named 07.jpg, 09.jpg, and so on, fetches them all, and displays them together as a neat, browsable gallery in a new tab.

There's no manual work involved. Right-click any image on a page and choose "Fusk", or paste a URL directly into the browser toolbar — Fuskr does the rest. You can choose whether to look forwards, backwards, or both from the current image, and pick how many images to include. It works with photos and videos alike, and handles websites that use leading zeroes in their filenames (e.g. 001, 002, 003) without any fuss.

Create a gallery of images based on one image that contains a number by incrementing and decrementing the images.

For example, if you were at example.com/images/08.jpg, then you could click the icon in the omnibar which would allow you to create a ready-made gallery of all the images found!

=== How to use ===

1: On your desired image, right click and choose 'Fusk'
2: Choose which direction:
● '+/-' will return a gallery with images that come before and after it.
● '+' will return a gallery with images that only come after it.
● '-' will return a gallery with images that only come before it.
3: Now choose how large you want your gallery to be - 10/20/50/100/200/500 or 'Other' (you choose!).
4: Your gallery will appear in the tab next to your current one. If an image isn't returned (404 or some other error), it will be hidden from view, but you can toggle that too!

=== Why 'Fusk'? ===

https://en.wikipedia.org/wiki/Fusker - Fusker is a type of website or utility that extracts images from a web page, typically from free hosted galleries. Fusker software allows users to identify a sequence of images with a single pattern, for example: http://www.example.com/images/pic[1-16].jpg.
