ComfyUI Node: SaveImage (Simple)

SaveImage (Simple):

The easy imageSave node is designed to simplify the process of saving images generated during your AI art creation workflow. This node allows you to either save the images directly to your local storage or preview them before making a decision. It is particularly useful for managing and organizing your generated images, ensuring that you can easily access and review your work. The node supports various output types, including hiding the images, previewing them, or saving them with a specified filename prefix. This flexibility makes it an essential tool for AI artists who need to manage their image outputs efficiently.

SaveImage (Simple) Input Parameters:

images

This parameter represents the list of images that you want to save or preview. The images are typically generated by other nodes in your workflow and passed to the easy imageSave node for final processing. The quality and content of these images depend on the preceding nodes and their configurations.

filename_prefix

The filename_prefix parameter allows you to specify a prefix for the filenames of the saved images. This helps in organizing and identifying the images later. For example, if you set the prefix to "artwork_", the saved images will have filenames like "artwork_1.png", "artwork_2.png", etc. There is no strict limit on the length of the prefix, but it should be concise and descriptive.

output_type

The output_type parameter determines how the images will be handled. It accepts the following options:

• "Hide": The images are not saved or previewed.
• "Preview": The images are displayed for preview without saving.
• "Preview&Choose": The images are displayed for preview, and you can choose which ones to save.
• "Save": The images are saved directly to the specified location. The default value is "Save", ensuring that your images are preserved unless you choose otherwise.

prompt

This optional parameter allows you to include a text prompt or description that will be associated with the saved images. This can be useful for keeping track of the prompts used to generate specific images, aiding in future reference and organization.

extra_pnginfo

The extra_pnginfo parameter is an optional dictionary that can include additional metadata to be embedded in the saved PNG images. This metadata can contain various details about the image generation process, such as settings, parameters, and other relevant information.

SaveImage (Simple) Output Parameters:

images

The images output parameter returns the list of images that were processed by the node. Depending on the output_type selected, these images may be saved, previewed, or simply passed through without any changes. This output allows you to continue using the images in subsequent nodes or workflows.

SaveImage (Simple) Usage Tips:

• To keep your saved images organized, use a descriptive filename_prefix that reflects the content or purpose of the images.
• Utilize the prompt parameter to embed useful descriptions or prompts within the image metadata, making it easier to track and reference your work.
• Experiment with the output_type parameter to find the best workflow for your needs. For instance, use "Preview&Choose" when you want to review multiple images and select the best ones to save.

SaveImage (Simple) Common Errors and Solutions:

"Invalid output type specified"

• Explanation: This error occurs when an unsupported value is provided for the output_type parameter.
• Solution: Ensure that the output_type parameter is set to one of the following valid options: "Hide", "Preview", "Preview&Choose", or "Save".

"Failed to save images"

• Explanation: This error can happen if there is an issue with the file path or permissions when attempting to save the images.
• Solution: Verify that the specified file path is correct and that you have the necessary permissions to write to the location. Check for any typos in the filename_prefix and ensure that the directory exists.

"No images provided"

• Explanation: This error occurs when the images parameter is empty or not provided.
• Solution: Make sure that the images parameter contains a valid list of images generated by previous nodes in your workflow. Ensure that the preceding nodes are correctly configured to produce image outputs.
