To add an image to your site just drag-and-drop the Image Element icon to where you would like it to display on your webpage [insert icon image]. The element box will prompt you to add a new image. You can then upload a new file or choose an existing image from your media gallery.
Dimensions will display in the top-left corner so you can resize your image to your desired height and width. If you hover over the image, further options for cropping, linking and adding a caption will display, as well as image settings for adding alt text.
