ComfyUI Node: Save Image If True (Mikey)

Save Image If True (Mikey):

The Save Image If True node is designed to conditionally save an image based on a specified condition. This node is particularly useful when you want to automate the saving process only under certain circumstances, thereby optimizing your workflow and storage management. When the save condition is met, the node utilizes the SaveImagesMikey class to handle the image saving process, ensuring that your images are stored with the desired filename prefix and additional metadata if provided. This functionality is essential for AI artists who need to manage large volumes of generated images efficiently, saving only those that meet specific criteria.

Save Image If True (Mikey) Input Parameters:

image

This parameter accepts the image that you want to conditionally save. The image should be in a format recognized by the node, typically an IMAGE type. This is the primary input that the node will evaluate based on the save condition.

save_condition

The save_condition parameter is an integer that determines whether the image should be saved. It accepts values of 0 or 1, with 0 meaning the image will not be saved and 1 meaning the image will be saved. The default value is 0. This parameter is crucial for controlling the conditional saving logic.

filename_prefix

This parameter allows you to specify a prefix for the filename under which the image will be saved. It accepts a string value, and the default is an empty string. This is useful for organizing saved images with a consistent naming convention, making it easier to identify and manage them later.

prompt

This hidden parameter can be used to pass a prompt associated with the image. It is not required for the basic functionality of the node but can be useful for adding context or metadata to the saved image.

extra_pnginfo

This hidden parameter allows you to include additional PNG metadata when saving the image. Like the prompt, it is not required for the basic functionality but can be useful for embedding extra information within the saved image file.

Save Image If True (Mikey) Output Parameters:

This node does not produce any direct output parameters. Instead, its primary function is to save the image to a specified location if the save condition is met. If the condition is not met, it returns a dictionary with empty filename and subfolder values, indicating that no image was saved.

Save Image If True (Mikey) Usage Tips:

• Ensure that the save_condition parameter is correctly set to 1 if you want the image to be saved. This is the key control for the node's functionality.
• Use the filename_prefix parameter to organize your saved images systematically. This can be particularly helpful when dealing with large batches of images.
• Consider using the hidden prompt and extra_pnginfo parameters to add valuable metadata to your saved images, which can be useful for future reference or further processing.

Save Image If True (Mikey) Common Errors and Solutions:

Invalid image file: <filename>

• Explanation: This error occurs when the provided image file does not exist or is not accessible.
• Solution: Verify that the image file path is correct and that the file exists. Ensure that the file permissions allow for reading the image.

Save condition not met

• Explanation: This is not an error per se but an indication that the save_condition parameter was set to 0, so the image was not saved.
• Solution: If you intended to save the image, make sure to set the save_condition parameter to 1.

Filename prefix too long

• Explanation: This error occurs if the filename_prefix provided is excessively long, which might cause issues with file system limitations.
• Solution: Use a shorter filename_prefix to ensure compatibility with your file system's naming conventions.
