How to store BLOB in MYSQL database of size more than 1M?

By default, in MySQL we can store BLOB of size 1M. To increase the size of this you have to change the my.conf file.
You can find my.conf file in Program Files\MySQL\MySQL Server 5.0\my.ini
Open the file and Under the [mysqld], add the following line.
max_allowed_packet = 16M
eg:
[mysqld]max_allowed_packet = 16M
