Apologies that this is off-topic.
Can't see the image. Not sure if I should be grateful or appalled.
I cannot see the image? this happens on so many forums
I had this issue as well, maybe what I discovered will help one of you:
I use Google Chrome, and with some images the show button did not work.
However, if I opened the page in incognito mode the show button worked fine.
This got me thinking...the only significant difference between regular chrome and incognito mode when it came to rendering the page was that incognito mode does not load extensions.
So, I disabled all my extensions and reloaded the page...Voila, the show button worked!
I then reenabled the extensions one by one, reloading the page after each one and finally got to the one that caused the problem.
In my case it was an extension called Disconnect, which blocks the trackers that monitor online activity, including those from major sites such as Google, Facebook and Twitter.
The image that was not loading in this case was loaded from a twitter domain (twimg.com).
As soon as I disabled the blocking of tracking by twitter the image was unblocked and the show button worked.
