- Keep only single photo preview per inline (large version 800x800) - Removed all_versions_preview display from photo inlines - Cleaner, more focused admin interface - Confirmed all sizes are stored correctly: * Large (800x800) verified * Medium (400x400) verified * Originals verified - Use large_url() for preview in admin (best quality/size balance)
