In webmail, I am regularly confused when I want to download an email attachment but I am offered three or more attachments from which to choose.   The extra "attachments" are either company logos or useless icons for "follow us on Facebook/Twitter/etc.   This is not how other email clients behave.

It appears that SM is offering attachments based on the presence of a filename, rather than based on "Content-Disposition: attachment"

I would be fine with an option to "display inline images for selection" if you think these are sometimes wanted.
