What's this?
When I want a bunch of links or pictures on a webpage and the only difference in the filenames is a number I can use this to write the link once, substituting the numbers with for example "NUM". The Javascript will generate all the links I need and I just have to copy and paste. Saves me time.
Example:
Input:
images/pictures/exampleNUM.jpg, images/pictures/exampleNUM_thumb.jpg
Output:
images/pictures/example01.jpg, images/pictures/example01_thumb.jpg
images/pictures/example02.jpg, images/pictures/example02_thumb.jpg
images/pictures/example03.jpg, images/pictures/example03_thumb.jpg
etc...
What's "Offset"?
If I want , say, picture 01 to link to picture 02 then I have to get the number 02 in there somehow. You can change offset to any number, it will then be added to the original number.
If you find this page useful you can also download it for offline use, there are no external files.
