I am making a managed package that contains an app that uses a document type image as a logo. I use the same logo on a VisualForce page in the same package, but that file is actually stored as a static resource.
I would like to only include the file once in the package, so I want to delete the static resource image, and simply reference the document image in the VF page.
I read that I can use the tag, and the url should be in the form : " /servlet/servlet.FileDownload?file=xxxxxxxxxxx" where xxxxxxxxxxx is the the unique id of theDocument/Attachment record containing the image.
Would that ID stay the same if I add the image to a managed package and it gets installed on a different org, or would the new org have a copy of the file with a different ID?
