Why did you ask this over and over ?
You need to write a HTTP Handler that pushes out the bytes of the bitmap from the DB. It would typically take the id of the image in the DB on the URL, read it and then do a BinaryWRite of the data. Your src tag would contain the URL that loads the image from the DB

Hello everyone.
I have a little application in which there are some main pages, and some detail pages for each main page.
in the detail page there is a button which gets you back to one of the main pages.
the main page, in the OnLoad method, there is a method which saves the page thet led you there (using HttpRequest.UrlReferrer).
I need the main page not to store the urlreferrer of the detail page, passing null as urlreferrer value.
I know javascript does this, but for some reason i cannot use it - and i am forced to do everything server-side.
Is there some method which sends you to one page, without passing its own url?
I googled about it and found lots of pages about people complaining that Response.redirect has this behaviour. I tried, and to my dismay, found that in my application works flawlessly - that is NOT what i want. I need Response.redirect NOT to work, thus passing null as the HttpRequest.UrlReferrer value.
I know this is at least confusing, but please try and see if you can give me an hand.
Thanks in advance.

This looks odd. Changing the value sent on referrer can't be done AFAIK. BTW, why you need such a solution ?

It is a long story.... 
Anyway, i do not need to change it. I just need it to be null, and i know there are some situation in which HttpRequest.UrlReferrer is null.
Example:
typing a new url in the address bar
using browser history
using javascript...
I need something like that, just server-side. I read around that Response.Redirect has sometimes this behaviour, but not in my case.
Any ideas?

I think you cannot do it in server.
Whether Main and Detail page url has any pattern.
If it has then use it to check whether its detail or mail page and work with that.
Else, i think HttpRequest.UrlReferrer cannot be set null from Server.
Also have you tried using
Response.Headers referrer property to null

Dim strExcelConn As String = ExcelConnection
Dim dbConn As New Data.OleDb.OleDbConnection(strExcelConn)
Dim strSQL As String
Dim delimeter As Char() = {"\"}
Dim splitter As String() = strpath.Split(delimeter)
Dim file As String = splitter(splitter.Length - 1)
strSQL = "SELECT * FROM [" & file & "$]"
dbConn.Open()
Dim cmd As New Data.OleDb.OleDbCommand(strSQL, dbConn)
Dim dsExcel As New DataSet

I'm sorry. It's plain this task is beyond you and you should just give up. Certainly asking again as you did, under a new account, is very rude.
For the third time. The file is on the client. It's not on the server. That is your error. You have the file as a byte stream, so you need to save it to the server, and then use that path ( which, unlike the path you're using, will be valid on the server ) to load the file in Excel.
I'm sorry, even if you get past this, I'd say you need to abandon the work you're doing and read some books on ASP.NET, to get you some basic understanding so you're able to understand clear help when it's offered to you. And, you need to learn some manners too. Creating a new thread, with a new account, when someone is trying to help you on the thread just below it, is just plain rude. I'm sure you have a job that you're incapable of doing, and you're feeling the pressure because you're inadequately prepared for the task at hand. But, this is not our problem. I have stuck with this because I am trying to help you, but I did this despite the way you presented yourself, not because of it.

Whatever - it seems odd to me that he posted, I answered, then you posted the same thing. Either way, I hope between you, you've managed to understand my explanation, I really would recommend you both do some reading, because the basic nature of ASP.NET seems to have escaped you.

How can two people working together not have communicated to each other that they were both posting the same question on the same forum, sounds strange to me.
Anyway there are plenty of tutorials out there and like Graus said a book one probably be useful for you to understand the basics of asp.net works.

Because .NET requires you use a batch file to import. Don't forget to call System.Batch.File.Run.ReallyRun.LikeNow("foo.bat");.

The problem is you don't understand what ASP.NET is, at all.
You get a filepath from your client, then you try to read the file on the server. Unless the server and client are the same machine, that isn't going to work, the file just isn't there.
SAve the file to the server file system in order to read it. Of course, this presents it's own problems, if you have more than one user at once and the file names clash, you'll be in trouble. Use Path.GetTempFileName ( something like that ) to work around that, or just File.Exists when you're saving it.
