Hello,

Thanks, I have displayed the images which them was stored in a Oracle's BLOB field, with:

<dtml-call expr="RESPONSE.setHeader('content-type','image/jpeg')"> <dtml-in SQLMethod_with_a_Only_Row> <dtml-var expr="BLOB_FIELD.read()"> </dtml-in>

However, I would like to resize this image. I can not do it with the "height" and "width" attributes, because the image is obtained from a Oracle's BLOB field, and no from image object (i.e.: I can not use <dtml-var "ImageObject.tag(border='5', align='left')">).

How can I do it ?

You have to set the height and width atributes of the tag you are generating for the browser to view the image. It is not the responsibility of the BLOB reading method to set the width and height atributes of the img tag.

cheers, Leo

I'm not really sure when this was asked ( I dont think it was '99) :)

The <img> tag is in the containing document, not the actual method which returns the image... Somewhere else you have an <img src="myZopeUrlWhichReturnsAnImage"> which is where you slap the height and width tags.
