Newbie need help in making a forum thread generator :x

Hi guys.. newbie at this thing. Im in need of your help, please help me.
This is how the program goes...

I will put the needed info on the text boxes. Then once i click 'generate' button, other info will be added like on the end and it will show on the textbox [the big textbox-i just added wrote those info.]

ive been googling and searching on youtube for some tutorial but cant find any. TIA

 

I am not sure if being able to put that is possible but an alternative would be add the image tags into the text boxes and then just put your image link in between the tags.

 

Look in to using POST data to your advantage. Unfortunately, to block the use of advertising bots, many forums have hidden or have discontinued the use of obvious POST data instructions that could be manipulated.
