How to get images from R2 to CF images
Hey, I want to upload large images to R2 (average Image size ~20MB). How can I copy these images to CF images for delivery? Workers won't be able to handle this.

What exactly are you trying to do? CF Images has a hard limit of 10 MB.
You can serve images from your bucket with an R2 Custom Domain. If you need to resize them, I would use Image Transformations, which can work off images in your bucket and has a max size of 70 MB

In my case R2 is only a temporary storage and eventually will delete images from R2 and keep the original images on AWS deep archive.
I'm using R2 as my first distention because of the low egress, these images will need to be transferred to multiple destinations.
I understand that CF images have a hard limit if 10mb that's why I'm asking if there is any way I can resize these images to be under 10mb so I can move them to CF images.

I'm trynna delete the images from R2 because of the storage cost, I'll be storing a large number of images every month, so I wanna keep a version of the images on CF images for delivery and keep the original copy on AWS archive (1tb is ~$1). So images should be on R2 for 1 month then deleted from R2, in this case I need an easy and cheap way to deliver these images to clients.
Hey @Chaika Could you give me a quick rundown on how you did this? I wanna use image resizing on R2 but since it merged with Images I don't know how to
Exactly, the docs are sht. Honestly, unless you are pro Cloudflare Dev, you have no idea how to achieve such simple tasks. Why are so few examples in docs?
