ComfyUI Node: FolderToImageStorage

FolderToImageStorage:

The FolderToImageStorage node is designed to streamline the process of loading and storing images from a specified folder into a global storage system. This node is particularly useful for AI artists who need to manage and manipulate large batches of images efficiently. By leveraging this node, you can easily import images from a folder, ensuring they are correctly oriented and converted to a format suitable for further processing. The node handles various image formats and ensures that each image is stored in a normalized format, making it easier to work with in subsequent steps of your workflow.

FolderToImageStorage Input Parameters:

key

The key parameter is a string that serves as an identifier for the set of images being loaded. This key is used to store and retrieve the images from the global storage. It is important to choose a unique and descriptive key to avoid conflicts with other stored images. The key should be a single line of text without any special characters.

folder

The folder parameter specifies the name of the folder from which images will be loaded. This folder should be located within the input directory defined by the system. The node will search this folder for images with supported extensions and load them into the global storage. The folder name should be a valid directory name and should not contain any special characters.

FolderToImageStorage Output Parameters:

This node does not produce any direct output parameters. Instead, it populates the global image storage with the loaded images, which can then be accessed by other nodes in your workflow.

FolderToImageStorage Usage Tips:

• Ensure that the folder specified in the folder parameter contains only images with supported extensions to avoid errors during the loading process.
• Use descriptive and unique keys for the key parameter to easily identify and manage different sets of images in the global storage.
• Regularly clean up the global storage using the ImageStorageReset node to avoid memory issues and keep your workspace organized.
