To change the image file type, click the Type drop-down menu [2].
To sort image files by date added or alphabetically, click the Date Added drop-down menu [3]. To search for an image, enter the image name in the Search field [4]. You must enter at least three characters for search results to display.
To embed the image, click the image file [5].
