Can someone confirm if webp is working as preview images in downloads?

[S77]

When I try to use a single webp image as a screen shot (preview image) in downloads app, after submitting I get an error. 
This is on 4.x 

Anyone else getting the same error?
Thank you in advance.

 used this file which works here in the forums but doesn't work in downloads app on THIS invisionbyte site if used as a single preview image. 
So didn't work for me on my site, and doesn't work on this site. I think something is wrong here.

I think it's a problem with the ImageMagick version installed:

• I tested on my local development server, and it was all good => ImageMagick v6.9.12-61
• I tested on my dev site on this server, and it threw an error => ImageMagick v7.1.1-43

oh no, That's the same error I get
is this something only IPS can fix? I don't think they will.

Either IM v7 changed how the data is handled compared to v6 (and thus IPS needs to implement a fix), or there's simply a bug in IM v7 in how the webp images are handled (not something IPS can fix).

 

Not sure which one it is, though. You can add the info above to your bug report and see what they say.
