A favicon is the icon that will appear in your browser tab.
This will need to be a .jpg, .png or .ico file and be of equal height and width (must not exceed 100×100 pixels).
Once you have logged into the Enjovia dashboard, click on settings > store settings and then make sure you are on the appearance tab.
Once here, either click on the ‘Store Favicon’ image box and select your favicon, or drag and drop your image into the box. After you save the changes, the favicon will take effect.
