Is there à way to send à picture
depends if your using a smart phone no but if its a laptop kind of thing you have the 14th icon from the left (in the reply box) is a picture of a tree. click on that a small dialogue box opens and you can upload an image in the first page. The second page is for linking an image uploaded somewhere else e.g facebook or picassa.
If your on a mobile you can upload a picture somewhere and give us the url (the address/ location of the image ) and then someone can link to it.
