Pictures in GMail

Somehow the blog you are looking at now seems biased towards Google... there is a lot of Google this and Google that. Here is another one: GMail now supports in-line images. You have to go through the Google Labs tab in GMail Settings to activate the feature. Then a new button shows in the Rich Text Edit Bar (see the gray arrow below). There are some image manipulation options as shown in the picture below - essentially the same as offered by Google Sites for editing web pages. The image is apparently not send but stored at mail.google.com. Works well for me - but what's the limit, and can one remove obsolete pictures? Here is the URL for the picture in the message below to check it out.
