Too vague. No mention of what application is at work here.
An answer could be to use IRFANVIEW to convert what you have to JPG ( http://www.google.com/search?&q=IRFANVIEW ) and attach them to some email. But the word "send" and "sending" could mean via an Intant Messenger so my answer may not apply.
