This sounds like a very useful plugin, thanks for writing it.
However, I'm afraid the friends I have/want to blurt out formulae to aren't at all interested in installing stuff on their machines (probably, they don't know how to either).
If you have time to look into this, I'd be grateful
But I understand if you don't have that time on your hands and I'm prepared to look into Plus! Plugins myself, but before I start, I'll ask you this first; would it be possible to adapt this plugin to send the pictures as normal file transfers instead of inline pictures? (And do you allow people to do it?)
In any case, thanks for your time and this great plugin
(By the way - I haven't installed it yet, I only use MSN Messenger (7 actually) and I'm keeping track of developments via this topic; I only saw the screenshots sending it as inline pics
)
