There is a plugin for firefox, which checks the addresses of sites that have the same image.
How to implement this in PHP?
As always, I am interested in the principle, otherwise I couldn’t even parse the query string for Google. = (

  • Checks sites previously known or looking for sites on which there is a stolen image? ZY I ask as I only use it for cross-browser compatibility. Therefore, I do not know the plugin like this) - Palmervan
  • In this particular case, they are known in advance, and their number is rather small. The problem is that the pictures can be "slightly" different - they are flip-flopped, cropped, compressed and so on. Another big problem is that the site on which the script runs is fluorinated. that is, it is on it with more likely stolen content from the specified list of sites. There are VERY many pictures for a person (several thousand or tens of thousands). - knes
  • I don’t know whether there will be a theme in the theme, there is a script that imetiruet search bot, ie, it scans html pages. If you roll in there a couple of regulars with arrays of pictures, then I think that what you need will turn out. In short, it is definitely necessary to twist it to fit your needs. - Palmervan 2:42
  • If through Google, then just continue to parse the query string) As I understand it, it is necessary that the starting site be indexed, and Google should be sent like "try a list of pictures similar to this (address)" And if "for pkhp", I would forget php I was looking for hosting with cgi and codil on it. For the search for "partial matches" on php, especially if there is no indexed list of pictures, this is for you yo-ho-ho, two boxes of rum and on vacation until the search is completed) - Sh4dow

There is a tineye service with its API , but it is charged. On php, everything is dark. There is an idea to divide the images into parts and average the color values. Or rotate and average. Then write to the database, say, for 4x4, 16x16 and 32x32 partitions and + -20, + -10 and 0 turns. And then, having collected the database, you can already compare the values ​​with the desired picture ...
That's just all this is dull, and I'm not sure that php is suitable for these purposes.

    At the moment I am browsing the Google JS library of this plugin. Perhaps this will help.
