ImagePaste is an add-on that enables copying and pasting images directly between the system clipboard and various editors within Blender. Users can paste images into the 3D Viewport as reference images or planes, into the Image Editor, into the Shader Editor as Image Texture nodes, and into the Video Sequence Editor timeline. The tool handles file management by saving pasted images to a temporary folder initially, and then relocating them to a designated folder alongside the .blend file upon saving. The add-on includes configuration options for customizing the save directory, naming conventions using predefined date and time variables, and determining which image types are moved when saving the project.
