Frizzly allows you to use your own share icons instead of those provided with the plugin. To do that you need to define a theme and then choose it in the settings of a certain module (e.g. hover settings).
Go to the Themes menu item under the Frizzly menu item.
Add a new theme.
Configure the theme.
The title of the theme will help you identify it later, so make sure the name is descriptive, especially if you plan to use multiple themes. After setting the title you need to configure the theme. First, you need to set the width and height of the buttons. Please note that each button needs to be of the same size you declare here. Once that’s done, you need to provide URL addresses of images you want to use. You can do that either by simply pasting URL addresses of images in the text boxes or by clicking Find image button. The second one will allow you to upload and choose images using the standard WordPress Media Library.
The theme configuration process is over. Now you need to hit Publish button, just like you do with blog posts. At this point we’re almost done.
Use the created theme
Now let’s get back to the module where you want to use the theme you just created. If it’s the hover module, go to its settings and choose your newly create theme from the dropdown list (remember it must be published to be visible on that list!). Now you just need to press the Save Changes button on the bottom of the settings page. Mission accomplished – your own share icons will be used instead of the theme-provided ones!
