[19:06:01] <jawr> hey, i'm getting the following error: Not a valid numbers of quantization tables. Should be between 2 and 4.

[19:06:15] <jawr> when trying: file_fd.save(file_io, format('JPEG'))

[19:06:51] <wiredfool> what version are you using

[19:07:29] <jawr> PIL-1.1.7-py2.7.egg-info

[19:07:48] <jawr> try an update?

[19:08:19] <wiredfool> well, my first though with any strange jpeg stuff is more than one version of pil/pillow installed

[19:08:38] <jawr> aha

[19:08:48] <wiredfool> is file_fd a Image object?

[19:09:29] <jawr> yeah

[19:10:14] <jawr> could it be an issue with reading/writing to that dir/file?

[19:10:33] <wiredfool> what's file_io"

[19:10:42] <jawr> file_io = StringIO.StringIO()

[19:10:47] <wiredfool> ok

[19:11:17] <wiredfool> is it one specific jpeg that doesn't work,

[19:11:22] <wiredfool> or is it any jpeg?

[19:13:56] <jawr> right, think i have figured it

[19:14:10] <wiredfool> and is format('JPEG') returning something like JPEG?

[19:14:18] <jawr> one of the users is uploading .png files :/

[19:14:26] <jawr> and it's thinking they are JPEG

[19:14:30] <wiredfool> that might do it

[19:16:03] <jawr> hmm, some jpeg files still doing it also

[19:16:07] <jawr> let me try reinstall PIL

[19:16:16] <wiredfool> especially if the save is triggering a read of the underlying image, and you're specifying the file format somehow, and it's reading a png as jpg

[20:21:54] <jawr> thanks for your help btw wiredfool

[20:22:05] <wiredfool> sure thing
