Subject: [PATCH] Images always failing - results in no images

The property `_values` was misnamed as `values` causing the function to always consider image retrieval a failure, often not offering an alternative. Discovered this problem while working on PressForward. This simple fix should resolve a ton of problems, most notably #29.
