I created a document on Indesign CC and sent it to people with Indesign CS4. I sent the .idml file as well. However they are getting the message: "This document contains 74 missing links to sources that are missing." I understand that these are the 74 images I used in the document. They are also not seeing most of the fonts on the document even though it isn't any fancy font. I am now uploading the folder of images used to send to them. Will this itself allow them to see the document properly?
File > Package and then put the .idml file in the package folder. Send that, and they should see both images and fonts.
With CS4? I'd send a PDF, too because the chances of it looking totally
correct are slim. And I don't think CS4 had a document fonts feature so the
fonts would need to be installed.
