Hi kyrathaba, thanks for the link. I'm interested in similar image related apps.
I knew about Gazopa
but haven't used them in some time.
When I last checked, TinEye performed the best for me (ie. most accurate) but I suppose individual results will vary. In the past these online image tools haven't been very reliable, but they continue to improve each year.
I will check some of the other tools mentioned in the comments. Thanks again.
