divide a single picture in several subpictures of the same size

[Helge]

Hello.

I got a question concerning ImageJ. I want to divide a single picture into 30 subpictures which are all of the same size. I can't find a command in ImageJ which could accomplish this problem. I tried to write a macro for that problem but with no great success. Therefore I want to ask is there a command I couldn't find until now or is there already a macro which could accomplish the problem.

Thank you in anticipation!

Best regards!
