Gemma3ImageProcessor.ReadImageDimensions now calls DecodeJPEG just to read width/height, which allocates a full RGBA buffer for every JPEG (width * height * 4) and then throws it away. This path is used during token-count expansion before inference (e.g., ModelService loops all msg.ImagePaths), so large or multiple JPEG inputs now incur an extra full decode and substantial transient memory pressure compared with the previous header-only PNG path, increasing latency and OOM risk for multimodal requests.
