Hi,
Thanks for reading my proposal.
What I can understand from your requirements is to copy forum posted images and then post them onto your one. This can easily be done with QTP, an automation tool. QTP let us navigate to the pages and then links, copy data from them, enter data onto the pages etc. With this we can read the images, save them to the disk and then upload to your forum. This will definitely suffice you requirements.
Can give a sample demo to get the basic idea, how QTP works to read and then enter same data to another website.
looking forward positively.
Thanks,
Ajit More
