As far as I know, just change the host address and the result will be the same. Try adjusting this line:
const imageLinkRegex = /https:\/\/i\.imgur\.com\/.*?\.(png|jpg|jpeg|gif)/gi
I don't know if it works on this host, but I know it worked on others. Try it.
Let's wait for TryNinja just in case. I guess the API key needs to be updated as well. If you use imgbb, you need to edit the API key in the code and enter your own. The API code is already set by default for your site, TalkImg, but it can also be edited. vgy.me surely has unique API codes as well.
