Set max_execution_time

I am having a problem where photo uploads are failing without warning. They fail after 30 seconds, which seems to be the max script execution time for php. I tried overriding this in htaccess but it didn’t work. How can I increase this time? And how can I detect when a file upload fails?

We can do it from server side, but need some more information here, like account/domain name.
So that we can check on which server domain belongs too. We request you to please open support ticket with required details and will do the needed.
