Add advanced media processing for images (e.g., resizing; ПП: скриншоты занимают юольшой объем места. Добавить сжатие)

この issue には説明がありません。

The issue mentions image processing for screenshots to reduce storage. Look for existing media handling in the Django backend, likely in models or views. Check if there's a file upload pipeline and where image processing could be integrated. Research libraries like Pillow for resizing and compression. Determine the expected output format and quality settings.
