Underground Blogger Method
Use HTML Landing Pages, and Squeeze Pages on Blogger
First, we have to change a bit on your HTML file or CSS files.
All of the image locations in your CSS or HTML file have to be changed to an external link.
You have to upload all of your images that your file uses to Blogger or an image hosting site. e.g. imgur
Once you have uploaded all your images to a site, replace your image codes in your css or html file.
Look for the codes that have your images, e.g. (background.jpg) and replace them with the image link.
