adobe photoshop - I need to slice one image into 50 different images automatically.

I have a big image that needs to be sliced into about 50 smaller images. I know there is a way to do it using 'guides' in photoshop and 'save for web and devices' options. I just can't seem to find any documentation on it

Answer

You could use ImageMagick?

convert -crop 100x100 original.jpg tiles_%d.jpg

were 100 is the tile size.
