+### Images
+
+Images placed in `images/` are copied to `output/images/`. By default picopaper
+strips metadata (EXIF, GPS location, XMP, PNG text chunks) from them during the
+build so nothing like camera model or GPS coordinates is published. The source
+files in `images/` are never modified — only the copies in `output/`.
+
+JPEGs are re-encoded with their original quantization tables (`quality="keep"`),
+so there is no quality loss. Animated images (GIF/WebP) and unsupported formats
+(e.g. SVG) are copied as-is.
+
+**Configuration in `config.py`:**
+```python
+STRIP_IMAGE_EXIF = True  # set to False to copy images byte-for-byte
+```
+
+Metadata stripping uses [Pillow](https://python-pillow.org/). If Pillow is not
+installed, picopaper prints a warning and copies images unchanged.
