Display Large Images
in [ASP]
|
From: cnote on 26 Jul 2006 12:01 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.

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.public.dotnet.framework.aspnet. -- Microsoft MVP - ASP/ASP.NET Please reply to the newsgroup. This email account is my spam trap so I don't check it very often.
