Non-SAP Images on ITSmobile screens

Hi out there,

a question I am thinking about for a certain time now is:

Is there a rather simple and quick way to put any images (Gifs) on an ITSmobile screen? And for example to switch it on or off under certain conditions?

I know how to change the "frame" by modifieing the CUAAREA.html, but how about the data screens itself ?

Is there any documentation out there, which possibilities there are to change the appearence of ITSmobile screens without buying a >10.000 € software package?

thanks in advance

Volker
