4. Accessibility: Ensure all images have descriptive alt attributes for better accessibility and SEO. This helps screen readers and improves search engine understanding of the image content.

5. Consistent Image Quality: Maintain a consistent quality and style for product images. High-quality, clear images can significantly impact purchase decisions.

6. Use Appropriate Formats: Choose the right image format for the context. For example, use PNG for images requiring transparency, JPEG for photographs, SVG for logos and icons, and GIFs for simple animations.
