APPLE INC. Preview no more. Mark up images directly within Yosemite's Mail app.
Mail Drop provides the means for sending large attachments. When you attach a large file (a video, presentation, or a folder full of images, for example) and send it, it's uploaded to your iCloud account. If the recipient is also using Yosemite's Mail they'll see your files as attachments, just as they always have. If they're using a different client or access email through webmail they'll see a link instead. Click that link and they can download the attachment. You can attach up to 5GB of files per message.
