Today a new feature was added to the Site Builder Uploaded Images widget, the ability to change the size and aspect ratio of the image you use.
The main purpose this was added was for users uploading images as full page headers. The default setting for the uploaded image was to be set to 'xxlarge' which is 512px, but because the width of a page is usually wider than that the result would be grainy images that were less than ideal especially when the banner is the main theme for the page.
This new system allows a larger image size to be selected so a better quality image results. Check out the BEFORE and AFTER images below.
The BEFORE image was blurry because it was a small image stretched into a large container. The AFTER image is close to the correct size for the container so is much clearer.
A small new feature, but useful for anyone using the Upload Images widget for the Site Builder system.
