Details about OS/2 version thumbnail .EAs - OS/2 specific - concerning filesystem Options

[Guest_Andrew Graham_*]

I would like to write a utility to create image thumbnails and attach them as .EAs to the images - ideally a commandline utility that I can start and let it recurse through a series of subdirectories.

That way, when I start PMView, the thumbnails will already be in the File Open dialog, rather than having to create them.

To do this I would like to have more details about how PMView attaches thumbnails to an OS/2 file. I can examine the EAs myself and learn this; I suppose they are little gifs?

First: has such a utility already been written? and

second: if not, are there any "gotchas" that Peter can warn me about before I start?
