However, the problem I am now having is that I want to be able to store the names of these images into an SQL database, but I am having problems storing the image names - every time I try to store the image name the only name that gets stored is "array[name][1]" for example.
Does anyone know what I would put into the SQL query to make it store the image name properly?
Please help me here guys, thanks
