In Gmail, I can only cut and paste a picture from the web into the mail, but even then when it arrives in someone's Thunderbird, for instance, they have to click "show remote content" to see it embedded.
I can attach a local image to the email, but I want it embedded within the text of the mail.
Googling an answer tells me that I should "Click the Insert Image button in the message's formatting toolbar." but in the latest version of Gmail there is no "insert image button":
How can I embed a local image from my hard drive into a Gmail e-mail so that e.g. Thunderbird can see it embedded without clicking a "load remote content" button?
