Textures adding or changing Api for bedrock modding

Problem Statement: Bedrock Edition lacks a native way to import local PNG/JPG images into Add-ons (e.g., custom NPC skins, photo frames). On Android 11+, strict scoped storage makes manual edits inside root directories nearly impossible, causing texture bugs, duplicate storage bloat, and system file risks. Proposed Solution: An official Opt-In Texture Replacement API with a native UI button in pack settings: Developer Control: Creators explicitly whitelist customizable texture slots. Core assets stay locked. Safe System Picker: Players select images directly from gallery via Minecraft's native picker, bypassing system folders. Engine Validation: Minecraft auto-crops, downscales, and sanitizes images into memory cache. Addressing Critical Risks & Catches: Storage Bloat: Enforce a strict max 3MB file size limit and auto-downscale resolution (max 1024x1024) to prevent lag or crashes. Content Moderation: Apply local platform safety filters. Add a world setting toggle ("Allow Custom Client Textures"); unapproved images show a default fallback texture in multiplayer/Realms. Asset Protection: API is 100% opt-in. Core models and proprietary pack assets remain completely read-only. Sync & Stability: Textures save inside world/leveldb, streaming safely during session handshakes to avoid desync
