Since you’re using FAST-CLI, you can make blocks PNGs when compiling the project. Just use the -b flag with the build command.

Example:

fast build -b

Okay, I’ve downloaded it, written the API Key, and set the Expiration to 0.

What’s the next step? What should I do about the blocks?

Would you recommend a better tool? But it must be free, please.

Follow what I have shown here, and when ImageUploaded get the url and store it in your database

Going for cloudinary can be a better option, there this trick I used long time ago. Creating three or more account, creating a list of keys etc, and when needed to upload file, use pick random from list, remember this is abuse, but we’re trying to prevent bandwidth with 1 account.
