No, try making your mime type exclusive to what is prepopulated for imgur.
Just to test.
(video\/(3gpp|mp4|mpeg|quicktime|webm))|(audio\/(aiff|midi|mpeg|mp4))|(image\/(gif|jpeg|png))|(application\/((msword|vnd.openxmlformats-officedocument.wordprocessingml.document)|x-(7z|rar)-compressed|zip|arj|x-(bzip2|gzip|lha|stuffit|tar)|pdf))
TO this:
image\/.*
I think because you have all those other file types included, you couldn't apply the same markdown to all those filetypes aka: !image(file.zip).
So you need to set it for images only. Just my guess. Like I said, for me, it shows mark down exactly how you request.
Btw : really funny picture.
