1. I can't answer this question literally since I will not know how you will actually perform this.
2. I do know that you could:
a. E-mail the picture as an attachment which makes a smaller email than an "insert picture" in some HTML email.
b. Get IRFANVIEW. See http://www.google.com/search?&q=IRFANVIEW
i cant send pics via email cos they r to big oh do i change them from bmp to jpeg. it just tells me when i send try to send them try to resize
