+Place your painting PNG textures here.
+
+Naming: must match the `asset_id` defined in the datapack painting_variant JSON.
+  painting_01.png  → "asset_id": "zerolands:painting_01"  (1×1 blocks = 16×16 px)
+  painting_02.png  → "asset_id": "zerolands:painting_02"  (1×2 blocks = 16×32 px)
+
+Size guide (1 block = 16 px):
+  1×1 →  16×16   2×1 →  32×16   1×2 →  16×32
+  2×2 →  32×32   4×2 →  64×32   4×4 →  64×64
+
+Rules:
+  - PNG, RGBA (transparent background = black in-game border).
+  - Width/height in the JSON must match the actual image ratio (W×H blocks).
+  - For each new painting: add a JSON in the datapack AND a PNG here.
+
+After adding files:
+  1. Rebuild the resource pack:  cd resourcepack && ./build_pack.sh
+  2. Re-upload the zip and update resource-pack-sha1 in server.properties.
+  3. Run `/datapack enable "file/zerolands"` in-game (already enabled if server restarted).
