Thank you very much for your help!

bonne question. l’idee de mon client.je dois trouver un moyen de le faire.

What?!

In InDesign..! I want that to happen automatically.

InDesign CC

when I do that I lose the image and its caption in my epub. they disappear..

I research more and it seems to be only in the HTML that I can do it. There is no way to do that in InDesign?

Second question: if I do it in the HTML, and later my client wants a change and I have to open the InDesign and make a change, do I lose then all the changes I did in the HTML?
