How do you post the coordinates of the optical recognition image when you buy an item? Aka, what does the address look like? I assume you just tag on the offer and coordinates of the click to the haggle page but I am not sure.
use a packet sniffer and you'll see in the post data x=345&y=234 and the replace tose with the ocr x and y
Your title was "What is the POST for <input type="image">?" The post for input type image actually depends on the NAME attribute in the input tag. The POST data is of the format: name.x=[x coordinate] name.y=[y coordinate] So for the image <input type="image" name="mypicture"> the an example of the data sent would be: ?mypicture.x=12&mypicture.y=232 It just so happens on neopets, they neglected to provide a name attribute for their input, so it defaults to simply ?x=&y=
