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.
The API code is just for the script to upload to TalkImg.
The script does not use other API codes, it just takes the image link and sends it to TalkImg via API.
Note this explanation:
Imagine that I have images on Imgbb and I want to transfer them to TalkImg, is it possible?
Forgot to reply this one, sorry.
Yes, you can. I've added a imageLinkRegex variable at the top. It currently only matches imgur links ending with png, jpg, jpeg (edit: and gif).
If you want to match ONLY imgbb images, you can use:
/https:\/\/i\.ibb\.co\/.*?\.(png|jpg|jpeg|gif)/gi
If you want to match BOTH imgbb and imgur images:
/https:\/\/i\.ibb\.co\/.*?\.(png|jpg|jpeg|gif)|https:\/\/i\.imgur\.com\/.*?\.(png|jpg|jpeg|gif)/gi
