Summary Card picutre showing in mobile app but not in any browser

[BumbershootSupp]

Hi,

The picture in summary card is not showing in any browser I have (IE, Mozilla, Chrome, Safari). However is does show in the mobile app. It also shows in the Card Preview Twitter Card Tester on the Card Validator page.

In the same browsers, other’s Tweets that contain summary card content do show the picture.

I have reviewed the tags and compared them to URL’s that do seem to work, but cannot find any reason for the discrepancy.

Here is an example of a URL: http://bumbershootdesigns.blogspot.com/2013/12/the-25-days-of-christmas-cards-day-23.html

Thank you for your help.

The image is too small to show up on twitter.com. It should be at least 120x120px.
