I would like to display announcement images before the service starts. I want them to be timed and to loop. I tried to do that with LibreOffice Impress, but I didn't get either timing or looping. I could manually click from one image to the other.
A side issue with Impress is that, in OpenLP, the title at the top of the images was black, rather than having the background display through the whole image the way it looks in Impress.
