Hello,
Could you tell me what kind of forum you are using? VBB, phpBB, Xenforo?
Could you send me the target site which you want to scrap its article?
What happens when inside the article have the image? You want to display image or url text link?
We will create a PHP script then run with cron job, that means you can set the time to trigger the script (hourly, daily,..).
Look forward to hearing from you.
