I see many members haven't discovered an excellent tool added by Google: searching by an actual image (not by a text).
1. Go to Google Images
https://www.google.com/imghp
2. Click on the little camera-image in the search box, on the right
3. Paste the url (try it out for example with
http://forum.axishistory.com/download/f ... &mode=view) and click "Search by image"
- or go to "Upload an image" and find the image in your PC
You will get a thumbnail-list of most websites with such a photo. Very helpful if you're searching for a source, additional info, a different size or sometimes a better copy of the image (sometimes it doesn't work, if an image has too many little details, like a crowd, or is in a really bad shape; I assume all this will be improved in the future).
Cheers,
Ivan
