There is no imageExtractor, how to solve it ?

[bartmachielsen]

The problem is that the used Boilerpipe version (that is downloaded in the background) is outdated and misses the image extractor implementation. To fix this you need to clone the boilerpipe project (google hosted version) and compile it into a jar and implement it in the project. I did this myself and posted the new version online: https://github.com/bartmachielsen/python-boilerpipe.
