Hi, It looks like there is an issue with the image loading on Roblox or when sent through the webhook. If you try to open the image link directly, it returns a ‘page not found’ error. I am not sure If that’s an engine bug as I haven’t seen any posts about this issue yet.
No need to be rude (you may not mean to be rude but by saying “Apparently” it really seems quite rude. There is no need for it.) . I was just guessing as I have never seen anyone using that URL outside of a Roblox experience.
