Display Large Images

[cnote]

I am trying to upload large images ( around 4 mb) from the server to show on
the client. Currently I'm using an http handler to do it and breaking it
into chunks sending it 1 mb at a time. Sometimes I'm getting errors, like
the page won't load. Any solutions on how this is done right? Thanks for
your help.

"http handler"?
Is this a classic asp or asp.net question?
If the latter:
There was no way for you to know it (except maybe by browsing through some
of the previous questions before posting yours - always a recommended
practice) , but this is a classic asp newsgroup. ASP.Net bears very little
resemblance to classic ASP so,
while you may be lucky enough to find a dotnet-knowledgeable person here who
can answer your question, you can eliminate the luck factor by posting your
question to a group where those dotnet-knowledgeable people hang out. I
suggest microsoft.publi c.dotnet.framew ork.aspnet.

This worked for me (I was running into the 4MB ceiling too) (Thanks to
Jason Withrow's contribution to ASP101
which helped me get started on downloading files)

Response.Buffer = True 'I didn't try "False"
Const BufSize = 2097152 '2MB "chunk"
Dim i
Dim objstream
Set objStream = Server.CreateOb ject("ADODB.Str eam")
objStream.Open
objStream.Type = adTypeBinary
objStream.LoadF romFile strFilePath
strFileType = lcase(Right(str FileName, 4))

' Feel Free to Add Your Own Content-Types Here
Select Case strFileType
Case ".doc"
ContentType = "applicatio n/msword"
Case ".jpg", "jpeg"
ContentType = "image/jpeg"
:
: 'other cases
:
Case Else
ContentType = "applicatio n/octet-stream"

End Select
Response.Charse t = "UTF-8"
Response.Conten tType = ContentType
i = 1
Response.Binary Write objStream.Read( BufSize)

Response.Flush
while not objstream.EOS
objstream.Posit ion = (BufSize * i)
Response.Binary Write objstream.Read( BufSize)
Response.flush
i = i + 1
wend
objStream.Close
Set objStream = Nothing
