Modifying an php module to Xoops

I have an xoops ads module that I have earlier made som custom change to. People kan insert into 10 pictures but now I want my clients / people that register to also have the oppertunity to add up to 3 videos to their ads. In admin section * must there be possible to decide how many videos the people can upload to their add like with the picture. * deside file types like they can upload. * deside file size It shouldn be an complicated job for an experiend php developer since all the basic function is there today. ## Deliverables LAMPP enviroment
