+**Auto-resize:** Images larger than 2000x2000 pixels are automatically resized to fit within this limit for better compatibility with Anthropic models. The original dimensions are noted in the context so the model can map coordinates back if needed. Disable via `images.autoResize: false` in settings.

 **Inline rendering:** On terminals that support the Kitty graphics protocol (Kitty, Ghostty, WezTerm) or iTerm2 inline images, images in tool output are rendered inline. On unsupported terminals, a text placeholder is shown instead.
 
 Toggle inline images via `/settings` or set `terminal.showImages: false` in settings.
