MacOS Mail Anti Inline Plugin

The plugin solves situations with awkwardly inlined images when sending images to anyone who is not using Mail App. If you want your images to appear as attachments to your recipients then this plugin is for you. It also prevents Mail auto-preview feature and display attachments as icons by default. It does something similar to what Attachment Tamer used to do.
