Problem uploading files larger than 30K

[Kimmy4]

Hi guys,
I am trying to upload a jpg file to a server but keep getting a web exception. Now the error occurs when i write the line httpwebrequest.getresponse and i've tested the status of the error and if displays a message when comparing the status to webexceptionstatus.timeout.
When i output the message in the exception it says:

An error message cannot be displayed because an optional resource assembly containing it cannot be found.

Now this only appears to happens on files larger than 30K and i was wondering whether anybody had come across this problem before or be able to help me with my problem.

If you need to see my code to upload then i will gladly supply it.

Thanks in advance for any help
