Thanks. Tried the plugin but the results were not very good. However, found this Chrome plugin: https://chrome.google.com/webstore/detail/dajedkncpodkggklbegccjpmnglmnflm. It gave me [a lot] better results (just in case someone is looking for a similar tool). I was thinking in making some kind of script to auto-check categories, but I don't think that would be reliable/useful as a human should still check the results :S.
Several communities have struggled for the WMF to help get Yahoo! BOSS Search API keys to automatically look for text copyvios and as far as I know they've always failed; I don't know if Google Images has APIs or how they work and I seem to remember an unfavourable discussion about TinEye as service: anyway, this is something we should really work on but which is probably not going to happen within a month.
