- Image size अनुकूलित करें - Annotation से पहले बड़ी images resize करें
- Photos के लिए JPEG का उपयोग करें - छोटे file sizes, तेज़ loading
- Graphics के लिए PNG का उपयोग करें - Diagrams/screenshots के लिए बेहतर गुणवत्ता
- Lazy loading सक्षम करें - बड़े datasets के लिए
- Thumbnails पर विचार करें - List views में previews दिखाएँ
- Pre-process consistently - Sizes और formats normalize करें
