I'm new to Umbraco and I need to know how to insert an image with a link/url?
For example -->
<a href="http://somesite.com"><img src="/map/image.png"/></a>
UPDATE: Below is a screenshot which doesn't show any button to insert an image.
In the editor? Just insert the image, then select it and click the link button.
In Umbraco 7, using the grid, you have to go to Developer section and locate the datatype(s) used for the grid property you are using. There should be an option to customize the rich text editor buttons somewhere in there.
