When you have to send a graphic designer a document, make sure it's made with a program from Microsoft Office. PC version if possible. If you have to send pictures, you'll have more success in driving them mad if, instead of just sending a jpeg or a raw camera file, you embed the pictures inside a Microsoft Office document like Word or Powerpoint. Don't forget to lower the resolution to 72 dpi so that they'll have to contact you again for a higher quality version. When you send them the "higher" version, make sure the size is at least 50% smaller. And if you're using email to send the pictures, forget the attatchment once in a while.
