When we drop any link of facebook wall, it extract all the images & some amount of text from that link & shows in user’s wall.
Can any body help me to clear my following doubt about it…
[1] I want to know how facebook wall script work. Is that go that link & scrawl the whole page or follow some other procedure.
[2] After getting all the data[images+text] from that link , is that script take out the images from the source location to it’s server & crop that image according to it’s specified size…
[3] or, it’s just dynamically show the image on the facebook wall by on-d-fly cropping image from source location(original image location)
