Hello,
Thanks for reaching out! You can link an image rather than using an icon if you preferred. To link an image, you can go to the Visibility tab for the button over on the right rail, click on the Icon section, then select "Image" from the Type drop-down menu. Once Image is selected, click on "Select Image" to add a link to the image you want to use:
You can link a PNG, JPEG, or SVG image file (GIF can't be used). You can pick from a few different animations for a menu button though, these are available on the visibility tab for the button group:
Hope that helps!
