It is done by using the PHP function
void set_time_limit ( int $seconds )
If seconds set to zero, no time limit is imposed.
Use the below resource:

We can store images and videos as well by converting the picture or audio/video into  the byte array using C#/ VB and store it in a database as binary file (set the type of the field as binary).because at the end every file is a binary so if you store it as binary it will definitely works!
