Attachment Tamer(Formerly known as Mail Attachments Iconizer) gives you control over attachment handling in Apple Mail. It fixes the most annoying Apple Mail flaws, ensures compatibility with other email software, and allows you to set up how attachments are displayed and sent. Attachment Tamer can: display (and print) images, PDFs, audio and video as icons with an optional file size limit and exceptions, send messages compatible with Microsoft Outlook, Exchange and other software, preventing the superfluous "ATT0001" attachments, send images as regular attachments, making it easier for the recipient to manipulate the image files, send images embedded in HTML layout and safely mix embedded images with other attachments, display full attachment names regardless of length instead of truncated names, prevent unwanted image resizing or set a default size for automatic image resizing.
What's new in this version:
compatibility with the OS X 10.9.5 (Mail 7.3) update to the same extent as previous pre-release builds code signatures updated according to 10.9.5 and Yosemite Gatekeeper security requirements
