One of the cool new features, that will make its way in the Q3 2009 RadControls for ASP.NET AJAX service pack release, is the additional thumbnail option in the Image Manager dialog. When you select an image, that ends with a specific suffix (e.g. "_thumb"), and there is an image with the same name but without the suffix in the current folder, the image dialog will offer the ability to automatically create a link to the original and open it in a new browser window. Here is how this will look like:
We hope that this will provide a much quicker way to do a task that will otherwise require either opening a new Link manager dialog or manually modifying the HTML content. Even though the new features are visible only if you click on an image with a specific suffix, there is a way to turn them off completely via the editor server API:
Setting EnableThumbnailLinking to false in the Image Manager properties will disable the two new checkboxes altogether.
