My database is Firebird.
I have a Web Server connected to a database. When I need to put some data into database, I develop a cgi application. The application receive data from a client application and put this data into database.
Can I use this method to put an image into database?
I known to make this with text data. How can I make with image ? Can you send me an example ?
You can send me your threathed sample with source. I need this because my client application is freezing during the 'upload data' routine.

- What database (SQL Server, Oracle, mySQL, ...)?
- What ports are blocked by your firewall -- or is the database port opened?
Your database being behind a firewall does complexify the problem. Most of the time, direct access to remote database server is not that secure and is restricted by the routers/firewalls. Sending the image to the database is not difficult in most of the cases nor is it to do it in a threaded way. Difficulty is that, if you don't have access to the database, well...
I can make you a threathed sample with source for mySQL quickly if you need so but I'll need more info about your firewall. By the way, you're better not posting the address of your server here if you give info about your firewall.
You should also think about sending the file by FTP and posting the path to the image in your database. Do you absolutely need to post the image directly to the database (this is not necessarily wrong but is it what you want)?
Have a nice day! :)
