I believe the page previews are not stored in the IDML file (not 100% certain on that).
Sure they aren't. Among some other things. That's why idml is so significantly smaller than indd.
One can easily google it.
And: if you don't have links on your computer, you can do nothing about it... IDML contains no previews, your ID doesn't see original links to generate those previews from scratch.
However, if at some sunny day they meet (idml and external links) you get a brand new fully working indd file
... (if I don't have the links on my computer)?
If you don't have the original files, you are in a heap of trouble even IF you would have the previews. So this problem is moot.
If you don't have the original files, you are in a heap of trouble
it depends on workflow, I guess...
maybe that idml was sent to OP just for text edits, not for final output. Then technically he doesn't need those external links, but with screen previews layout looks much more "user friendly"... I'd like to work on regular indd in such case (with lores previews), if file size doesn't matter.
Thanks all of you, for answering. I guess I'll have to see over the workflow then, to find the best solution.
could be greeking...
check your display performance in preferences... might be set to Fast
playing with display performance settings has no sense, as long as you have no screen previews.
