Header or hero images are horizontal images displayed either at the top of your Folio or at the start of a Section.
Selecting the right image can be challenging as it displays horizontally on traditional browser (or devices held horizontally) but on most mobile devices it will display as a vertical image.
The images that work the best, for headers, are those with a horizontal orientation and that have been sized at 3000 pixels wide at 72 DPI.
It's best to choose images where the subject is not too large in the frame and is centered or near the center.
To check and see how your image may look when viewed on a mobile device check the layout by clicking on the view options below the edit area.
Left to Right the icons represent the following devices
