When I started posting in my blog on wordpress.com I didn’t know how to insert an image in the post. I found a button in editor’s tool bar to insert images but it does not have facility to browse an image file from the local machine. But we can add a image url for which the image needs to be stored in some file server. I asked many of my friends but I could not get the solution to directly browse from computer.

Finally myself found this feature on wordpress.com. On the top of editor’s tool bar there is another tool bar labeled “Add media”. The first button is to browse an image file either from local computer or file server (Url). This helped me posting a blog with example screen shots.

Take a look at following screens to learn how to insert images.

You can upload not only images but also videos and audios.
