## How it works
This workflow does watch out for new images uploaded within Google Drive.
Once there are new images it will download the image. And then run some logic, remove the background and add some padding to the output image.
**By default Images are saved as .png**
Once done upload it to Google Drive again.
## Features* Select Google Drive Credentials within the Google Drive Nodes
### This workflow supports
* Remove Background
* Transparent Background
* Coloured Background (1 Color)
* Add Padding
* Choose Output Size
## Customize it!
* Feel free to customize the workflow to your needs
* Speed up the workflow: Using fixed output size
### Examples
* Send Final Images to another service
* For Products: Let ChatGPT Analyze the Product Type
* Add Text with the \"Edit Image\" Node
