I'm not sure. I think it was a .png, but I'd have to go to the Minecraft wiki where I got it. (It's an isometric view of a warped wart block, that I chose after I chose WarpedWartWars as my nickname.)
Edit: It's a .png. This is it:
Edit 2: And it was happening with all Scratch profile pics that I tested.

Hi!
In nothing smarter .. but I try to comment on something ..
It is not a "png" issue, it's about CORS (Cross-Origin Resource Sharing).
Firs of all, I guess you see the "workaround" (the IDE message point to this). Just download those pictures to your computer, and then, upload them to Snap! with no problems.
And why? Because you are "dragging and dropping" a resource from another domain, and if that domain has not CORS allowed (this is the case), you can't do this (do programmatic things with content of other domains in your domain). It is a security feature (to prevent phishing attacks)
This issue can appear by doing other actions (with sounds, using the url block ...). We need to know about this, and about "using directly" web content.
Another thing (we can think about this) is about our forum CORS. We will do (think about) it!
Oh, right, now that I re-read the error message I see that it does say "cross-origin." I was too focused on "tainted," which has a special meaning for vector pictures.
