Getting Started
After installing the plug-in an additional preference pane will appear in the Mail Preferences window. You can view it by choosing Mail > Preferences…, then clicking on the arrow to the right of the toolbar icons in the window and choosing Attachments. This is the control center of Mail Attachments Iconizer. If you want to know what the Iconizer can do for you, take a look at the options.
Apart from this, you will be able to work with the attachments in the same way as before: If you wish, you can have the attachment displayed in place by selecting the option View in Place from the attachment context menu (you can open the menu by control-clicking on the attachment) and you can iconize attachments that are viewed in place in the same way. But with Mail Attachments Iconizer, Apple Mail will respect your choice, remember it and send the attachment with appropriate content disposition.
If you have a specific question or problem, try looking in the index or problem solutions.
