I am aware of how to *produce* graphics in different formats for different export backends. I use your first approach, which I think is the better solution. Here, I am after a solution, that works on images that are not produced but merely included via [[file:./some.pdf]]. I think there should be the possibility to include these into html (and odt) export without any user interaction. So, I - do not want to write a source block just to produce the by-backend image - do not want to change the link manually - do not want to run the converter manually I am pretty sure this should be achievable with standard orgmode tools (like filters, export hooks, or anything). Since 'this is coming again and again' it seems a non-esoteric task. And as there is 'no solution out of the box', I assume(d) that somebody has written these filters already. Regards, Andreas
