help with adding an image to SQL database (using c# and ASP)

Asked by SASKPEN in Programming for ASP.NET, C# Programming Language, SQL Server 2008

Tags: c#, ASP, SQL server 2008

Hello all,
I am designing a website that a user can add an item to a classified section. I have put a lot of work into this site but....I have reached a stand still. grrrrr
Anyways, here's my problem (i think)
I am trying very desperately to add an image along with some other data to my database--but nothing is being added. There are no errors (that I know of) But it kicks me to my error page without adding anything to the database. The only thing I can figure out is that I have completed the "image" section wrong.

The items are not getting input into the database
Yet....there are no major errors found. it just shoots off to my error page and does not add anything to the database.

* all images are declared as an object now....yet I am still trying to upload to UploadImages folder.
* Is this right?
* even if I am not uploading an image -- it still does not work.
* Could this give me issues of trying to get stuff in my db?

I have never actually added images in this way. (could be a big issue, could be a small issue...hey, it may not even be my issue - who knows? Do you? Can you help me please?)

Do I have to add something to my web config file?? The only thing I have actually changed/added is my connection string.

Thanks in advance for your help....I really appreciate it.
