Issue: Currently, there’s no way to rotate screenshots (e.g., 90° left/right) directly in Steam’s upload interface. For example, if you take an in-game portrait-style screenshot by rotating the camera, the image appears sideways when uploaded, forcing users to edit it externally first. This is inconvenient, especially for frequent uploads.

Solution: Add two rotation buttons (↻/↺) in the screenshot upload window—similar to social media or messaging apps. This would save time and streamline the process."

"This feature already exists in Discord and most smartphone galleries—Steam could adopt the same user-friendly standard."

"Implementation should be lightweight since it only affects the preview display, not the original file."
