For images that fill the entire background, we recommend using a resolution of 1800 pixels wide and 1600 pixels high, and file size less than 200KB to minimize the loading time of your blog pages. Google only supports JPEG, GIF, and PNG format images.
After uploading a photo, you will see additional options that are not available for the built-in images: Alignment, Repeat, and Scroll options.
- Alignment: You can adjust horizontal (left, center, right) and vertical (top and bottom) alignment of your background image.
- Repeat (Tile): If you have a small image, you can have it repeat horizontally and/or vertically to fill the page. Otherwise, we recommend that you choose a page background color that blends in with your background image.
- Scroll: By default, your image stays in place while readers scroll the page contents. By selecting the “Scroll with page” option, both the background image and page contents scroll together. We recommend that you use an image that blends into your background color or set your image to tile vertically if you choose this option.
This feature is only available on Blogger in Draft for now.
