El Capitan Mac Mail is not sending pasted images
We recently upgraded our computers to El Capitan. Since then, we've noticed an issue that is affecting our workflow. We take screen snapshots then paste them into new Mac mail messages. The image shows correctly until you send. At that point, the image is lost and just shows the "image not found" icon. (The question mark). I can look at my sent message and have examined the message source, and the image looks like this: <img src="webkit-fake-url://963fe40b-5ab7-414e-a11c-5c1cdbe19e3e/image.tiff" class=""> which is obviously not right. Since this used to work in previous versions, is this a bug?
