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=20=

returns the image...  Somewhere else you have an <img=20
src=3D"myZopeUrlWhichReturnsAnImage"> which is where you slap the height=20=

and width tags.

The <<img> tag is in the containing document, not the actual method
which returns the image...  Somewhere else you have an <<img

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=A0from image object (i.e.: I can not use
<<dtml-var "ImageObject.tag(border=3D'5', =
align=3D'left')">).</smaller></fontfamily>
