ComfyUI Node: Image History Loader

Image History Loader:

The Image History Loader node is designed to facilitate the retrieval of previously used images from a history database. This node is particularly useful for AI artists who frequently work with a set of images and need a quick way to access their past work without manually searching through directories. By leveraging a history database, the node ensures that images are easily accessible and can be loaded efficiently. This functionality is beneficial for maintaining a streamlined workflow, allowing you to focus more on the creative process rather than managing files.

Image History Loader Input Parameters:

image

This parameter specifies the name of the image you want to retrieve from the history database. The image name should match the one stored in the database. If the image exists in the history, it will be loaded and returned; otherwise, a default blank image will be provided. This parameter is crucial for identifying and loading the correct image from the history.

Image History Loader Output Parameters:

IMAGE

The output is a tensor representation of the loaded image. If the specified image is found in the history database, it will be converted to a tensor and returned. If the image is not found, a default blank image tensor will be returned. This output is essential for further processing or analysis within your AI art workflow.

filename

This output provides the filename of the loaded image. It is useful for keeping track of the image's origin and for any subsequent operations that may require the filename. If the image is not found, the filename will be returned as 'null'.

Image History Loader Usage Tips:

• Ensure that the image names you provide match exactly with those stored in the history database to avoid loading errors.
• Regularly update your history database to include new images you work with, ensuring they are easily accessible in the future.
• Use the filename output to keep track of your images and maintain an organized workflow.

Image History Loader Common Errors and Solutions:

The image <image> does not exist!

• Explanation: This error occurs when the specified image name does not match any entry in the history database or the image file has been moved or deleted.
• Solution: Verify that the image name is correct and that the image file exists in the expected location. Update the history database if necessary to reflect any changes in file locations.
