Twitter cards. Wrong image in web, but right image in mobile application

[Tigrrus]

We have following twitter card:

DraftKings - Daily Fantasy Sports for Cash

It displays correct image in validator, and in mobile twitter application.

However, on twitter website it displays our logo:
https://twitter.com/tigrrus/status/386047877769736192

Here is markup:

    <meta name="twitter:card" content="summary">
    <meta name="twitter:domain" content="kountermove.com">
    <meta name="twitter:title" content="Killer Kountermove Fan">
    <meta name="twitter:description" content="You love Kountermove...We love you back with the Killer Kountermove Fan medal">
    <meta name="twitter:url" content="http://www.kountermove.com/badge/18/">
    <meta name="twitter:image" content="http://www.kountermove.com/media/badges_titles/Killer_Kountermove_Fan_1.png">

Our summary cards were working nice, and were showing correct image till redesign of our site. After redesign we met problems, but markup was not affected. Tell us, where to dig?

Hi Tigrrus,

This is likely because:

1.) The image provided in twitter:image is less than 120x120. If you resize, it’ll show up properly.
2.) As a result, we’re pulling from the fall back og:image, which is the image you’re seeing.
