@s-molinari backgrounds are in the layout files. I have different layout because my project contains mini systems.

@metalsadman Thank you so much sir… I will try it later.

Background image in each layout does not change unless you refresh the page. I have different layouts of different pages, each layout has different background images too, but every time I load new pages the background image from the previous page retains, I need to refresh the page to load the right background image of the current page.
