Oops, I'm sorry the file was missing

I've uploaded the file, please try again.

le3on9 on Feb 10, 2009:

I'm still pretty new with PHP. So could you explain more about how to install this?

Nash on Feb 10, 2009:

Just include the file from your code. Maybe something like this:
  1. <?php
  2. include_once 'functions/http_files.php';
  3.  
  4. /* ...your code here... */
  5. ?>

Hi ...

i'm test ur script to upload local file to tinypic.com, my question is ..

how to take generated link?

regards

using cURL?

Nash on Mar 16, 2009:

That's cool, upload image to tinypic.com and retrieve the links. give me a day or two to write the code to do that.

mahfooz on May 16, 2009:

i want to download file using download dialog box, is it possible to use this script in this case???

Nash on May 17, 2009:

It's not possible since this is an automated script. If you want dialog boxes, use browsers instead

Nash on Jun 24, 2009:

Guys, I've made an advanced HTTP client. It is a utility for HTTP scripting. Using pure PHP, no curl or other dependencies needed.

@ghprod:
Check this script to upload images to TinyPic and retrieve the URLs.
