Hi

I was also wondering that

When you use an image in your template, it means it counts as an insert of an image in a template. Usually, transparent images can also count for your creation of your template. You add as many as you like unless it's gonna be a minimum of images you insert so it doesn't crash the browser. You also add your template in other templates too. So, That's all for this information.

Thanks for the explanation!

if you take the template and put it in an image, then it's an insert, because it's not actually using the template
