The Image Overlay Widgets allow you to show a persistent image on your stream. This can be useful if you want to have something like a sponsorship image appear on your stream or some announcement / notice that you always want shown.
When selecting an image via the Windows Open File dialog, multiple images can be selected. This will randomly pick one of the selected images each time the Overlay Widget is shown / refreshed.
You can optionally specify a width and/or height for the image or leave the fields blank and it will use the native size of the image when it's displayed. If only width or height is specified, it will use proportional calculation to scale the other based on what was specified and the actual size of the image.
The Image Overlay Widget can be set to automatically refresh the contents shown via the "Refresh Time" option on the Details tab.
