FI : Imgur currently blocking UK access to API

[TimTaylor]

FI - It looks like Imgur is no longer allowing access to the api in the UK. I believe (but have not yet debugged) this is leading to the following error. Here I've used the call plot(1:10)

This reprex appears to crash R.
See standard output and standard error for more details.

#### Standard output and error

``` sh

Quitting from wax-mouse_reprex.spin.Rmd:19-21 [unnamed-chunk-2]
Error in read_xml.raw(res) : Start tag expected, '<' not found [4]
```

Assuming this is due to the API being blocked, could a more informative error message get thrown.
