This is really helpful! Works like a charm for most cases, but a few are throwing exceptions - can you please handle the exception so that this rake task skips the problem ones (or better yet, prints them out so we can address manually) and finishes the ones that do work?

Here's an example image_url that causes the problem: 
https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSblZtV79FYAJ7Y1BdYK7egn_p0g6aB5s6Q4yUkpkQz1q0B7pmMow

And the start of the error when running the rake task: 
```
rake aborted!
redirection forbidden: http://encrypted...
```
