Unfortunately there isn't a way to do that with our theme unless you custom code something up. Sorry.
Gourav, I would really like to try this on Woodberry and Figero themes. How can I custom code something up?
For WoodBerry Theme Go to front-page.php present in your theme directory and remove the code from line no.9 to318 And replace it with Code: <img src="Enter your image address here"/> Now, Paste this code in Custom CSS Appearance > Theme Option > Styling Option > Custom CSS Code: .slider-container img { width: 100%; } This will solve your issue.
