You can make a pretend file-like object with the python module StringIO. Look in the Photo product for an example of this or try a snippet I did this morning: from cStringIO import StringIO # construct and upload a thumbnail fd.seek(0) im = PIL.Image.open(fd) im.thumbnail(thumb_size) outFile = StringIO() im.save(outFile, thumb_format, quality=thumb_quality) outFile.seek(0) self.thumb.manage_upload(outFile) self.thumb.manage_changeProperties(title=self.title or self.id) cheers, .flip.

Hello, I'm using PIL to convert bmp and tiff-images to jpeg. After conversion they should be added to Zope. My problem is that for conversion, I think, I have to safe them on the filesystem. Zope's security policy doesn't allow me to delete files with an external method. Am I forced to do a cron-job? Isn't it possible to change the format in another way?? Thanks very much!! I've heard that's easier to stream the images and convert them on the fly! Any hint?? Thanks.
