Dear list, I have the following situation, that I would like to solve using ConTeXt. I have to generate a bunch of PDF documents daily, that someone else has to validate (put a stamp on it [let’s put it that way]). It might be a physical stamp, but it might be also a vector image. One of the issues is that the stamp has a different place in each document (almost). Another issue is that the stamp should be added after the document is generated, not before. Having the following sample: \starttext I want this image replaced: \externalfigure[cow][scale=200] \stoptext After generating the document (and not modifiying or recompiling the source), is there a way to replace the image with another one? Many thanks for your help, Pablo -- http://www.ousia.tk
