After blogging about it yesterday, the Google Reader team fixed the image problem in under 24 hours. I can confirm that the same problem items are no longer affected. I even got a comment from one of the Google Reader engineers as follows:
Hi Mike,So, plus one respect point to Justin for personally informing me of the correction. He wasn't the problem, but he sure made a nice effort to fix things. Now, if the same could come out of the Blogger team.
Although we try our hardest to avoid bugs like this, occasionally one slips through. When a bug sneaks in, it's our top priority to find the error and fix it so our users don't have a bad experience.
You'll notice that the bug has been fixed, so please let us know if there's anything else you find amiss.
