Question about Ebanner

Hello all I'm new in nsis

Can i use ebanner plugin for background without BGGradient enabled?
I ask this because i like to start/stop background image.gif ,using function, only on MUI_PAGE_INSTFILES (only during install/copy files).

If we are talking about image on the screen background - window itself appear if BGGradient option presents. Another simple way for background window is BgImage plug-in. Or you should create this window and track all minimize/maximize situations.
