When building your overlays save your files as transparent PNGs to the sizes specified below using your favourite image creating program.
PNGs support the use of transparency which allows you to see the broadcast behind the overlays depending on the opacity chosen while creating the graphics.
JPEGs can be used if you don't need transparency in your overlays.
