Force Apple’s Mail to add images as attachments

One of the longest-standing complaints I see about Apple’s Mail app is that it places any images you drag into an email as inline images (which means the image appears in the email wherever you actually drag & dropped it) instead of as a standard attachment (which appears as an icon at the bottom of the email regardless of where you drag & drop it). The problem is that inline images (and PDFs) don’t always work well with all email apps on the receiving end. Some people complain that the image quality gets degredated, and in some cases the image doesn’t come through at all.
