     """Log an image on a cached per-topic channel.
 
-    Encoding is chosen from the frame's channel count and dtype:
-
-    - Single channel => depth map, logged uncompressed as ``16UC1`` (integer) or ``32FC1`` (float).
-      Plain ``uint8`` grayscale (with no ``depth_range``) is the exception and is sent as ``mono8``.
-    - Three channels => ``rgb8``.
-    - Four channels => ``rgba8``.
-
-    When ``compress_images`` is set, ``mono8`` and ``rgb8`` frames are JPEG-encoded instead; depth
-    and ``rgba8`` frames are always sent raw.
+    Frames are cast to ``uint8`` and the encoding is chosen from the channel count: 1 => ``mono8``,
+    3 => ``rgb8`` (float input assumed in [0, 1]), 4 => ``rgba8``; other counts are skipped with a
+    warning. When ``compress_images`` is set, ``mono8`` and ``rgb8`` are JPEG-encoded instead.
 
     Args:
         topic: Foxglove topic to log on.
         frame_id: Frame id stamped on the message.
-        arr: Image as HWC or CHW (CHW is transposed to HWC), any dtype. Non-depth floating-point
-            images are assumed normalized to [0, 1] and scaled to uint8.
-        compress_images: JPEG-encode ``mono8`` and ``rgb8`` frames; ignored for depth and ``rgba8``.
+        arr: Image as HWC or CHW (CHW is transposed to HWC), any dtype.
+        compress_images: JPEG-encode ``mono8`` and ``rgb8`` frames; ignored for ``rgba8``.
         channels: Per-topic channel cache to reuse (see :func:`_log_foxglove_scalars`).
         log_time: Message time in nanoseconds, also written to the header timestamp; when ``None``
             the server's receive time is used.
-        depth_range: ``(lo, hi)`` bounds that normalize depth to ``[0, 1]`` ``32FC1`` so Foxglove's
-            default panel scaling matches rerun's ``depth_range`` contrast (a ``RawImage`` carries
-            no value range itself).
+        depth_range: ``(lo, hi)`` bounds used to clip a single-channel frame before it is encoded as
+            a regular image.
