I have a pdf of a book cover that was created from an InDesign file.
It is a four-color book cover spread. I cropped the file and resaved with a new name to show only the front cover (the right side of the file).
I emailed this to a client and when they opened it, it showed the complete, uncropped version and the colors were missing.
I tested this several times and when the file is actually downloaded, it is correct.
But if it is "previewed" within the email client (AOL & Yahoo), this weird uncropped two-color version appears. I've been working with and emailing pdfs since Acrobat 4 and have never encountered anything like this.
Any idea what's happening?
