Disable inline viewing of attachments in Mavericks mail

Dear all

In previous version of the OS, there was an easy terminal fix to disable inline viewing of attachments in mail. Instead of bulky and cumbersome images and PDFs, I used to get nice, neat icons.

This terminal fix doesn't seem to work in Mavericks.

Online sources tell me to buy a separate app called Attachment Tamer to fix this.

Just wanted to find out whether there is a way to do this without additional software.

Thanks in advance

Best regards
