Improve image search and save

[jzohrab]

• see if can add a text box to refine image search results, sometimes the default search images aren't that great.
• possible to search by the parent term, instead of the child? e.g., if "dogs" has parent "dog", then the image search should be done with "dog".

Did part 2 (image search is done with parent term), but not part 1 (additional text box).

Parent term search is merged into develop.

Options:

1. add text box to image results page
2. add ability to import a jpeg file, so that users can do their own external searching elsewhere.

2 might be easiest ... add an "upload file" button to the bottom of the search results and post box, or something.

Fixed in develop, good enough for v1.0 of this:
