ComfyUI Node: Load Image Based on Number (Mikey)

Load Image Based on Number (Mikey):

The Load Image Based on Number node is designed to help you efficiently load an image from a specified directory based on a given seed number. This node is particularly useful when you have a large collection of images and want to select one deterministically using a seed value. The node ensures that even if the seed number is very large, it will wrap around the list of available images using the modulo operation, providing a seamless and predictable way to access images. This functionality is beneficial for tasks that require consistent image selection based on a numerical input, such as generating reproducible results in AI art projects.

Load Image Based on Number (Mikey) Input Parameters:

image_directory

This parameter specifies the directory where the images are stored. It should be a string representing the path to the directory. The node will search this directory for image files with extensions such as .png, .jpg, .jpeg, .webp, .bmp, and .gif. The directory must exist, otherwise, an error will be raised. This parameter is crucial as it defines the source from which the images will be loaded.

seed

The seed parameter is an integer that determines which image to load from the directory. The seed can be any non-negative integer, and the node uses the modulo operation to ensure that the seed value wraps around the list of available images if it exceeds the number of images in the directory. This allows for consistent and repeatable image selection based on the seed value. The default value is 0, with a minimum of 0 and a maximum of 0xffffffffffffffff.

Load Image Based on Number (Mikey) Output Parameters:

image

This output parameter is the loaded image in tensor format. The image is selected based on the seed value and is converted to a tensor for further processing within the AI art pipeline. This format is essential for compatibility with other nodes and operations that may follow.

filename

The filename output parameter provides the name of the image file that was loaded. This is useful for tracking and referencing the specific image used, especially in scenarios where reproducibility and documentation are important.

Load Image Based on Number (Mikey) Usage Tips:

• Ensure that the image directory path is correct and accessible to avoid errors related to non-existent directories.
• Use the seed parameter to consistently select the same image for reproducible results. This is particularly useful in experiments and iterative design processes.
• If you have a large number of images, you can use the seed value to cycle through them predictably, ensuring a diverse selection over multiple runs.

Load Image Based on Number (Mikey) Common Errors and Solutions:

Image directory <image_directory> does not exist

• Explanation: This error occurs when the specified image directory does not exist or is not accessible.
• Solution: Verify that the directory path is correct and that it exists. Ensure that the directory is accessible and that you have the necessary permissions to read from it.

IndexError: list index out of range

• Explanation: This error may occur if the directory does not contain any valid image files.
• Solution: Ensure that the directory contains image files with supported extensions (.png, .jpg, .jpeg, .webp, .bmp, .gif). Check that the files are not corrupted and are readable.

IOError: cannot identify image file

• Explanation: This error occurs if the node encounters a file that is not a valid image.
• Solution: Make sure that all files in the directory are valid images and have the correct file extensions. Remove or relocate any non-image files from the directory.
