Links are present and up to date
This check make sure all InDesign links are OK. No image links can be missing or modified.
‘Links’ are extra files which are referenced by an InDesign document. Although links can be other file types, such as text, typically links refer to images placed into an InDesign document.
Icons are shown under the status column in the Links Panel. (InDesign Menu > Window > Links) to indicate a problem
= Missing Link
Links can go missing if renamed, moved or your computer is disconnected from them if held remotely e.g. on a file server.
= Modified Link
Links become modified if edited outside of InDesign e.g. resized or colour adjusted in Photoshop.
Fix this problem by selecting the link(s) in the InDesign Links panel and choosing to update or relink.
