ComfyUI Node: 🖼️ Download Image from URL

🖼️ Download Image from URL:

The 🖼️ Download Image from URL node is designed to fetch an image from a specified URL and optionally save it to a local directory. This node is particularly useful for AI artists who need to quickly and efficiently download images from the web for use in their projects. By providing a URL, the node retrieves the image, converts it to a tensor format suitable for further processing, and returns the image along with its dimensions. Additionally, it offers the flexibility to save the downloaded image with a custom filename and in a specified directory, ensuring that your workflow remains organized and efficient.

🖼️ Download Image from URL Input Parameters:

image_url

This parameter specifies the URL of the image you want to download. It is a required field and must be a valid URL pointing to an image file. The node supports common image formats such as .jpg, .jpeg, .png, and .webp. If the URL is not provided or is invalid, the node will not be able to fetch the image.

save_file_name_override

This optional parameter allows you to specify a custom filename for the downloaded image. If provided, the image will be saved with this name in the specified directory. If the custom filename does not include an extension, the node will append the appropriate extension based on the image format. If not provided, the node will use the original filename from the URL.

save_path

This optional parameter specifies the directory where the downloaded image should be saved. If provided, the node will save the image in this directory. If the directory does not exist, the node will create it. If not provided, the image will not be saved to disk, but it will still be processed and returned.

🖼️ Download Image from URL Output Parameters:

image

This output parameter returns the downloaded image in tensor format. The tensor format is suitable for further processing in AI and machine learning workflows. The image is converted to RGB format to ensure compatibility with various processing techniques.

width

This output parameter returns the width of the downloaded image in pixels. It provides useful information about the image dimensions, which can be important for subsequent processing steps.

height

This output parameter returns the height of the downloaded image in pixels. Similar to the width parameter, it provides essential information about the image dimensions for further processing.

🖼️ Download Image from URL Usage Tips:

• Ensure that the image_url parameter is a valid URL pointing to an image file to avoid errors during the download process.
• Use the save_file_name_override parameter to organize your downloaded images with meaningful filenames, especially when downloading multiple images.
• Specify the save_path parameter to save the downloaded images in a specific directory, which helps in keeping your project files organized.

Error: Unsupported image format <file_extension>

• Explanation: This error occurs when the image URL points to a file with an unsupported format.
• Solution: Use a URL that points to an image in one of the supported formats: .jpg, .jpeg, .png, or .webp.

Error: Failed to fetch image from URL with status code <status_code>

• Explanation: This error occurs when the node fails to download the image due to an HTTP error.
• Solution: Check the URL to ensure it is correct and accessible. Verify that your internet connection is stable.

Error processing the image: <exception_message>

• Explanation: This error occurs when there is an issue during the image processing stage.
• Solution: Review the exception message for specific details and ensure that the image URL points to a valid image file. If the problem persists, check for any issues with the image file itself.
