I am writing a product that returns an image generated by pil (unfortunately it doesn't): Create image- im = PIL.Image.new('RGB',(width,height)) it is then drawn- draw = ImageDraw.Draw(im) draw.rectangle([0,0,width,height], fill=(250,250,250)) etc etc etc after it is ready to be sent out I "save" it - pic = cStringIO.StringIO() im.save(pic, 'GIF') and send it pic.seek(0) RESPONSE.setHeader("Content-type", "image/gif") RESPONSE.write(pic.read()) my index_html <dtml-var standard_html_header> <IMG src="./dynamicImage?RESPONSE=RESPONSE"> <dtml-var standard_html_footer> the product class inherits Item, Persistent and Implicit the dynamicImage method has an argument RESPONSE When I click on view all I get is an image placeholder box (true as well when using the same image tag in a dtml method in the root folder), however from a dtml method in the root folder <dtml-var expr="TestObject.dynamicImage(RESPONSE)"> will render an image as the only content. any other content in the method is ignored. This is my first attempt at a product, so after much hair pulling I must get it to work. Thank you in advance for any help Sean K --------------------------------- Do you Yahoo!? Yahoo!
