What can i do?

java.lang.IllegalArgumentException: image == null!

It seems the image selected does not exist. What image where you trying to download?

imgur links

i.ytimg

(as the video says)

but still not working

I don't think you copied over the video.

Either way, are you just copying the URL for the site, or are you right clicking on the image to get the direct url to the image?

I too am seeing this error, even though I'm using the direct url to the image. In the logs linked below, I used a picture from the PixelPrinter spigot page as a test:

Not sure if this is happening for the same reason as the original poster, but since I'm getting the same error message in-game, I assume I can put it here. This happens with any image I try.
