I'm a very new Publisher user, and have been using it to build a 180-page book with lots of images. I am having a lot of problems with performance and memory with Publisher. My book was initially laid out with Linked images, but I have seen a few posts here which suggest that maybe Embedded is a better way to go. So, if I change that setting in my document properties, I'm guessing AP isn't going to go and collect and embed all my linked images, right? If I change it to embedded now, does it affect any current images, or just ones that might be inserted from now on? If the latter, then I guess I would have to start again from scratch with it set to Embedded in order to change all the existing images. Is this the right assumption here, or am I missing something? The relative merits of Embedded vs Linked are very unclear to me, and nothing I've seen (yet) tells me WHY I should choose one over the other. I only chose Linked because I thought it should keep the Publisher file smaller, which I thought would be A Good Thing. But maybe not! If someone could clarify this, it would be a big help to me, and maybe others.
