Just noticed Rick's comment to use the file manager.
Where on a gallery forum you must use the image manager.
Once I fixed this:
The value is in bytes. Not mb or gb. so for say a 1 mb file you would enter 1048576
I was entering the wrong numbers. I did everything else also I was not entering enough to allow for the uploads. But working great now. You have to attach the file through the Image Manager and then upload it...thanks Rick and Reuben appreciate it.
