Saving a jpg into Postgresql table

Hi guys,

I have a projects using ASP.NET (VB.net) where i upload a jpeg file
using a web form and then save the jpeg file into a table. I've decided
to use "Oid" instead of "Bytea" as i heard that "Oid" is more memory
efficient. So can anyone point me to a website or link where i can see
the VB.net or C# code that does the SQL insert of the jpeg file into the
"Oid" data type column and also how to do a SQL select to retrieve and
display the image on a web form? Thanks
