How can I embed my images or links in the Adobe Illustrator file?
Rather than linking to a file that you’ve placed in a document, you can embed (or store) the file within the document. When you embed a file, you break the link to the original. Without the link, the Links panel doesn’t alert you when the original has changed, and you cannot update the file automatically. This is a good feature when sending files off to a printer because this ensures that the image(s) link's are not needed by a service provider.
Keep in mind that embedding a file, rather than linking to the original, increases the document file size.
Select a file in the Links panel, and choose Embed Image from the panel menu.
Select the linked artwork in the illustration window. In the Control panel, click the Embed button.The file remains in the Links panel marked with the embedded-link icon.
