I am a graphic designer for a company and we have a series of factsheets. I have made a master template for the factsheets (most of these factsheets are just 2 pages with minimal images).
However I am using icons for most and other photos at other times. Before I mass produce these from the template would it be better to just embedd the icons and link the odd image rather than linking every icon? I have to keep in mind that we may need our outsourcing designer to edit these files from time to time.
There's no difference in output quality. Linking keeps the ID file size small and allows you to easily edit the original—in your case you might not care about either.
