I've been Googling around the internet oceans in search of a piece of code that has a similar functionality as the Digg image fetcher. I've always wondered how this thing works exactly.
The thing is, you give it a URL. It then crawls the site for images, and gives them to you in a nice tidy way, with a ay a radio button next to each image. You select the one you like/want, and it discards the rest.
I just want the image fetcher, the rest is not that difficult. Oh and I don't need the whole code, just some general pointers to what I need to look for exactly.
Thanks for reading this, hope this is also interesting for other people.
You need to do this with a server side language like PHP/ASP/.NET or similar. I wrote one in PHP. I call this method 'Page scraping' Basically, using the URL you are given, you load the contents of the URL (the HTML) into a variable and search through the variable for image tags. You have to do some string manipulation to get each image tag out successfully, and then display them at the end by printing out each image.
I'm not sure you can do this solely with JavaScript but I may be wrong. Graham
I posted this in the javascript group because I didn't know exactly how it works. A php script is probably the best way.
Not to bother you much, if what you wrote is open-source could I have a link where to get it. If not, could you point me to a place where you found some info to write something like that.
