User blog comment:Harbumz/Introducing Vignette, Wikia's New Thumbnailer/@comment-3388044-20150306182511

On some wikia, we can Special:Upload a file using the URL. When I plug in a vignette URL to upload an image from one wikia to another, it fails.

I’ve tried reformatting the vignette URL differently. No luck.

How do I reformat the URL so that it will work at Special:Upload?

Thank you.
