Magento\Theme\Model\Design\Backend\Image

What it does

This class handles image file uploads for Magento theme design configuration settings in the admin panel.

It extends the base File class and restricts uploaded files to common image formats (JPG, JPEG, GIF, PNG).

Developers would use this as a backend model for system configuration fields that accept theme-related images like logos or favicons.
