Overlay Size Specifications

Image Overlays

When building your overlays, save your files as transparent PNGs to the sizes specified above using your favourite image creating program. 

PNG format supports the use of transparency which allows you to see the broadcast behind the overlays depending on the opacity chosen while creating the graphics.

JPG format can be used if you don't need transparency in your overlays.
