In order to do it, first you have to locate your images at any web server. You can upload it to free image hosting service like Picasa web album, Photobucket, ImageShack etc or to your own web host. After that you can insert the pictures from the web in an email, make sure the Yahoo mail rich text editor is enabled.
- Open your image in a browser, the one you upload to web server.
- Highlight the image using your mouse and press Ctrl + C (copy). If you right click the image and select "copy image" it doesn't work in Firefox, maybe it works for Internet Explorer. So better to highlight using your mouse and press Ctrl + C.
- Go to your Yahoo mail, put your cursor inside the email body where you want the picture to show up and then press Ctrl + V (paste). Yahoo has inserted the picture inside the email, you can continue typing your email after or before the image.
- You can also simply use ‘drag and drop’ to do this as an alternative way.
