Could try this...
Make a word document with your mail text.
Copy the picture you wish to send and insert it into the word document using paste or Ctl V.
Then size the picture as required.
Then create your mail with no text.
Use Ctl A to select everything in your word doc and Ctl C to copy it.
Then back to your empty mail and use Ctl V to drop text with picture as body of message.
Tips - When creating word doc do not put picture in first - have at least a couple of lines at the top. To size the picture click on it and drag a corner inwards or outwards as required.
