Window
Free PNG images in the category “Window”: 2 files with transparent background, no sign-up.
Windows as frames and as part of a scene: an open wooden casement wrapped in greenery and orange flowers, glazed entrance doors with an intercom, a snowy cabin with arched door, and interiors where the light falls through the glass.

Window, door, room
In the objects section, Window sits beside Mirror and Glasses as another thing you look through. Doors, bedrooms and building fronts turn up because a window rarely appears alone; it is usually part of a room or façade.
Frames for collages
An open window with transparent panes is a ready-made frame: drop a landscape or a portrait behind it. Check that the glass area is truly empty rather than tinted white, or the photo behind will look washed out.
Light and time of day
Sunlight through a window sets the mood of an interior shot. For a warm product scene, look for soft side light; hard midday light leaves strong shadows that are difficult to match when you add your own objects.
