ComfyUI Node: Pick Image From List (FS)

Pick Image From List (FS):

The FS: Pick Image From List node is designed to help you select specific images from a provided list based on certain criteria. This node is particularly useful when you have a collection of images and need to randomly or sequentially pick one or more images for further processing or analysis. By leveraging parameters such as seed, start index, and select amount, this node offers flexibility in image selection, ensuring that you can tailor the output to meet your specific needs. Whether you are working on a project that requires random image sampling or need to select a subset of images from a larger batch, this node simplifies the process, making it efficient and straightforward.

Pick Image From List (FS) Input Parameters:

list

This parameter expects a list of images from which the selection will be made. The list should be in a format that the node can process, typically a list of image objects or file paths. The length and content of this list directly impact the selection process.

seed

The seed parameter is an integer that sets the starting point for the random number generator. By setting a specific seed, you can ensure that the random selection process is reproducible. The default value is 0, and it can be any integer.

start_index

The start_index parameter determines the position in the list from which the selection process begins. If set to -1, the node will randomly choose a starting index. The value ranges from -1 to 32, with a default of -1. This parameter allows you to control where the selection starts, which can be useful for sequential or specific index-based selection.

select_amount

This parameter specifies the number of images to select from the list. The value ranges from 1 to 32, with a default of 1. It ensures that you can control the number of images picked, whether you need just one image or a batch of images for your task.

Pick Image From List (FS) Output Parameters:

IMAGE

The output parameter is a list of selected images. The function returns the images based on the criteria set by the input parameters. This output can then be used for further processing, analysis, or any other tasks that require the selected images.

Pick Image From List (FS) Usage Tips:

• To ensure reproducibility in your image selection process, set a specific seed value.
• Use the start_index parameter to control where the selection begins, especially if you need to pick images from a specific part of the list.
• Adjust the select_amount parameter based on the number of images you need for your task, keeping in mind the maximum limit of 32.

Pick Image From List (FS) Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error occurs when the start_index is set to a value greater than the length of the list.
• Solution: Ensure that the start_index is within the range of the list length. If unsure, set start_index to -1 for random selection.

ValueError: select_amount must be at least 1

• Explanation: This error occurs when the select_amount is set to a value less than 1. - Solution: Set the select_amount to a value between 1 and 32.

TypeError: list must be a list of images

• Explanation: This error occurs when the list parameter is not a list of images.
• Solution: Ensure that the list parameter is correctly formatted as a list of image objects or file paths.
