Question: how do I paste images into a post?

[mphelps]

Sorry for the naive question, but how do I paste images directly into my posts? When I use the "Attach Files" function, it puts thumbnails of my images into a box separate from the text of my email. This prevents me from putting captions with my images.

Again, sorry for the naive question.

I should add that I use a Mac.

Thanks,
Mike
