HOW TO USE REVERSE IMAGE SEARCH
1. Click the arrow by your post number.
2. Hover your cursor over "Image Search."
3. Click "Google."
4. Click on the thumbnail of one of the results - not the link, the image by the link.
5. This will bring up a screen with more information on that result.
6. Click "Search by image."
7. Now you should have lots more results.
8. It should show a thumbnail of the picture at the top of the screen, with the words "Find other sizes of this image:"
9. Click "All sizes."
10. Sometimes repeating steps 4-9 with this new set of results can find even larger sizes.
