Slice your images even in batch mode and make HTML pages with pieces joined, using TileMage Image Splitter

TileMage Image Splitter is a free and easy to use program that lets you slice an image automatically by defining a number of pieces (rows and columns).

The program can also create an html file with the pieces tiled to let them appear as a single intact image.

TileMage Image Splitter can process multiple image files in a single run (Batch Mode), and create an HTML table with the new tiles. 

You can customize naming patterns of the output files, and you can load and save your images in seven different formats.
