I need to make a method act like the clone of an image. Without extending the Image class...(I would like to do this in DTML or python-script) I am simply trying to get a method to return the exact data of an Image object, so it can be used in normal HTML <IMG src="myimage.jpg?somevariable">. If the Image is a method, it can execute some logic based on the QUERY_STRING.
example: DTML_Method "myimage.jpg" # should look and smell like a JPG to the browser (but also execute some logic without # effecting the image header data) ---- | <dtml-call "RESPONSE.setHeader('Content-type', 'image/jpeg')"> | <dtml-var expr="therealimage.data"> | <dtml-var somelogic> ---- But this doesn't return the proper data or Content-Length: "therealimage" is a standard Zope Image object.
Any help is greatly appreciated... -Trevor
