In most cases, webmasters use the same thumbnails provided by sponsors. Because of this, the same thumbnail can be on hundreds of sites and the differences are only nominal in thumbnail size.

This feature allows you to create completely unique thumbnails by slicing the thumbnail into several pieces. How this looks can be seen here http://demo.smartcj.com/category/Thumb%20split/

Setup is very simple:

1. In the crop profile in Thumb IM add a line that will slice the thumbnail into several parts

/usr/local/bin/convert {FILE} -crop 2x2@  +repage  +adjoin {FILE}_%d.jpg

In this case the thumbnail will be sliced into 4 equal parts (2×2) and saved with names file_1.jpg file_2.jpg etc

Modify the line to get a different number of pieces, or uneven pieces etc.

2. In the template add

<!--THUMB_URL_PART1-->
<!--THUMB_URL_PART2-->

and so on for each piece you created

In the demo 4 pieces were created and accordingly 4 tags were used to output these 4 pieces. Space was intentionally left between them so you could see this is not a single image, but several pieces.

This way you will get unique thumbnails that don't exist on other sites.
