Most of us start using Outlook for email as part of our first job. I started my career with a company which lives on Linux, completely, which I feel was really great experience for me.
I started using Outlook for email only on my third job, and one thing that I found interesting is the fact that I can copy and paste an image in to the body of the email, showing it inline, instead of an attachment. I will need few more steps if I have to have an image inside my gmail in the same way.
If you are using Google Chrome and Gmail, try copy pasting an image from a web page into the body of your email and you will have it there, inline. CTRL + C and CTRL + V also works !
btw, you can do this on firefox too, but its not really stable yet. Chrome works great with this gmail feature.
