Today I have finalized the work on Plonum, a Mac OS X application to convert images to iWork Numbers documents.
If you want to surprise your tax accountant with a fancy christmas card this year, then just plot your favorite christmas image with Plonum and send it to him or her. If your tax accountant uses Windows, you can also export the resulting Numbers document to Excel format
Please note that iWork Numbers has a limit of 256 columns, so Plonum can only process images with a maximum width of 256 pixels.
You can download it from the Downloads page.
