this is a great way to disincentivize people from running relays. thanks client devs!

If relay operators are surprised by base64 images, I got news. There are worse things being transfered in broad daylight through regular events.
I just open source a relay who run at cloudflare with workers. It was designed to help people run their relays with the cf's free plan.
With this relay, people can hold their events. and It has one GB for people to hold their base64 image event.
Maybe there also should be many relays are welcome people to send image event with payment.
