That was indeed the culprit. I had switched it off to speed up export. After
setting that to t again it works (of course). Drawbacks are, that I need to
confirm the evaluation in each export (I am a bit hesitant to generally
accepting src block evaluation), and evaluation takes time.

I do not really need src block evaluation during export. I only need to
evaluate (manually) when I changed the graphics src, what I am doing
anyway to check the changed image.

But how would I control the (not-)inclusion of the src code during
export in that case?

Thanks,
