ComfyUI Node: Image Save YC

Image Save YC:

The YC_Image_Save node is designed to facilitate the saving of images generated or processed within the ComfyUI environment. This node provides a streamlined method for exporting images to a specified directory, allowing for organized storage and easy retrieval. It offers flexibility in naming conventions through customizable filename prefixes, delimiters, and number padding, ensuring that your saved images are systematically named and easy to identify. The node supports various image formats, including PNG, JPEG, and others, and ensures high-quality output by default. By using this node, you can efficiently manage your image outputs, making it an essential tool for AI artists who need to save and catalog their work effectively.

Image Save YC Input Parameters:

images

This parameter expects the image data that you wish to save. It is the core input for the node, as it determines what content will be written to the file system. The images should be in a format compatible with the node's processing capabilities.

output_path

The output_path parameter specifies the directory where the images will be saved. If left empty or set to default values like none or ., the node will use a predefined output directory. This parameter is crucial for organizing your saved images and ensuring they are stored in the desired location.

filename_prefix

This parameter allows you to set a prefix for the filenames of the saved images. By default, it is set to "ComfyUI". This prefix helps in categorizing and identifying images, especially when dealing with large batches.

filename_delimiter

The filename_delimiter is used to separate different parts of the filename, such as the prefix and the numbering. The default value is an underscore (_). This helps in maintaining a clear and readable filename structure.

filename_number_padding

This parameter determines the number of digits used for numbering the saved images. The default is 4, meaning numbers will be zero-padded to four digits (e.g., 0001, 0002). This ensures that filenames are sorted correctly in file explorers.

filename_number_start

This option allows you to specify whether numbering should start from a specific value. It can be set to "false" or "true", with "false" being the default, indicating that numbering will start from zero.

extension

The extension parameter defines the file format for the saved images. Supported formats include png, jpg, jpeg, gif, tiff, webp, and bmp. The default is png, which is widely used for its lossless compression.

caption

An optional parameter that lets you add a text caption to the saved image. This can be useful for adding metadata or descriptions directly to the image file.

caption_file_extension

This parameter specifies the file extension for the caption file, defaulting to .txt. It is used when captions are saved as separate text files alongside the images.

prompt

A hidden parameter that can be used to include additional information or instructions related to the image, though it is not directly visible in the node's interface.

extra_pnginfo

Another hidden parameter that allows for embedding extra metadata into PNG files, useful for storing additional information within the image file itself.

Image Save YC Output Parameters:

images

This output returns the image data that has been saved. It confirms that the images have been processed and stored as specified by the input parameters.

filenames

The filenames output provides the names of the files that have been saved. This is useful for verifying the output and ensuring that the images have been named and stored correctly according to the specified parameters.

Image Save YC Usage Tips:

• Ensure that the output_path is correctly set to avoid saving images in unintended directories. This helps in maintaining an organized file structure.
• Use the filename_prefix and filename_delimiter to create a consistent naming convention, which can be particularly helpful when dealing with large numbers of images.

Image Save YC Common Errors and Solutions:

"Invalid output path"

• Explanation: This error occurs when the specified output_path is not valid or accessible.
• Solution: Verify that the output_path is correct and that you have the necessary permissions to write to the directory.

"Unsupported file extension"

• Explanation: This error indicates that the chosen file extension is not supported by the node.
• Solution: Ensure that the extension parameter is set to one of the supported formats, such as png, jpg, or bmp.
