Thumbnail Problem

What am I doing wrong in the JSON Feed that causes my thumbnail to just be color bars? I copied the code as directed, pasted it into a new browser window and it looks fine...but on the channel it's just bars. Sigh...long day of frustration!

Here's the JSON...line 723 is the thumbnail causing the grief.

Color bars is what shows up when I load "https://i.vimeocdn.com/video/742941601.jpg?r=pad" in a browser.

Re: Thumbnail Problem

I think adding the dimensions to the code did the trick. Not sure why, but Roku seems to want the sizing info included. Thanks for taking a look!

Re: Thumbnail Problem

It could be displaying a cached copy of the image.  You would want to purge the cache on your CDN and/or do a hard reboot of the roku with the power plug.  Also with lots of content it will load up faster if the graphics are already the size required, instead of making the roku device resize them to fit.
