Dear Stephan, Yes! It solved most of my issues. I did have to add converters for png and gif files too (nothing automatic…), but the result is fine, and it works without any further action required. And the final file is HUGELY smaller which is great. I still have some problems with inputting PDF files, but I will try to solve it alone first before asking for help. It is probably something between poppler and xpdf (to be checked). Thanks a lot for the prompt — and to the point — answer. Jacques
