This is very easy to solve! You don't need any S3 storage just to serve images. That's like using nuke to bomb an ant. Here is the solution:
Step1: Create a repository on your github account.
Step2: Upload an image (e.g. bot avatar) to your repository.
Step3: Copy the link of your image, then paste to jsdelivr (select "convert from Github").

Step4: Copy the JSdelivr link to your Typebot.

Now, you have a world-class CDN provider serving your image FOR FREE!!!
This link is permanent unless you purge it!
