> Hi all,

> I'm trying to make an external method that creates a thumbnail of an image
> on the fly. I want to give it the url of the image and return the image
> data. It should look something like:
> 
> <dtml-var "MakeThumb('/path/to/my/image.jpg', (64, 32))">
> 
> I figured out already that I should use a StringIO object to store the raw
> image data in, so that PIL has an object to work with. The only two things
> I'm struggling with still are:
> 
> - How do you get the data of the image in the StringIO object?
> - How do you return the thumbnail image?
> 
> Hope that somebody can help with this.
