A favicon is a small image that is displayed in the browser tab when visiting a web page.
You can use favicons with your landing pages and forms by using one of two methods:
1. Save an icon file to the root of the email module
This is the simplest method which applies the same favicon to all pages. You need a 32x32 pixel ICO file named favicon.ico.
If you don't have a suitable ICO file there are many tools to help create one. Or Vuture's front-end team can assist you.
Your Vuture Administrator will then save that to the root folder of your email module (also known as the root of exchange-sites).
2. Reference the icon file in your pages
This is a more flexible solution which allows you to use other file types such as PNG and GIF, and allows you to have different favicons for different templates or pages.
Using meta tags in your pages you specify the location of the icon file so this needs to be included in your templates.
This wikipedia article gives an overview of the different options.
As part of HTML you are also able to define a range of icon sized.
For Apple device support you should use the apple-touch-icon meta-tag which is also described in the article above.
