Embedding an image in the html?Hi;
Is there a way to embed images in the response rather than writing them to disk and having an <img ...> tag? And if so, how is it done and what browsers support it? -- thanks - dave You are unclear about the actual problem.
It's easy to substitute the SRC="" behaviour in ASP.NET and simply stream an image to the user. The stream data is up top you. Be clear..

But I was wondering if I could add the image to the response that contains the html - like a MIME email message. That way I don't have to track images that will be requested shortly and also determine when to dispose of them. -- Show quoteHide quotethanks - dave "Edwin Knoppert" wrote: > You are unclear about the actual problem. > It's easy to substitute the SRC="" behaviour in ASP.NET and simply stream an > image to the user. > The stream data is up top you. > > Be clear.. > > > "David Thielen" <thielen@nospam.nospam> schreef in bericht > news:E34D203A-31AB-4B55-9D90-0E31C4B40825@microsoft.com... > > Hi; > > > > Is there a way to embed images in the response rather than writing them to > > disk and having an <img ...> tag?

2397, you can include the image in as a base64 encoded. IE does not support rfc 2397. <img src="data:image/gif;base64,<base64 encoded image>"> -- bruce (sqlwork.com) Show quoteHide quote "David Thielen" <thielen@nospam.nospam> wrote in message news:E34D203A-31AB-4B55-9D90-0E31C4B40825@microsoft.com... > Hi; > > Is there a way to embed images in the response rather than writing them to > disk and having an <img ...> tag?

on browser type.

IMO, I don't quite recommend using the <img src="data:image/gif;base64,<base64 encoded image>"> since it's not a standard feature in html, also making image binary mixed with html content will cause the main page's size increase extremely..... I'd suggest you consider building an ASP.NET httphandler which help retrieving image stream from different soruce (database, file system, or dynamically through GDI+ code) and write them out as a single image stream ... Thus, any other pages can use <img src=xxxx> to reference that httphandler's url.... here is #A simple ASP.NET photo album http://weblogs.asp.net/bleroy/archive/2005/09/08/424714.aspx #Using ASP.NET HTTP Handlers to create a photo album http://www.microsoft.com/belux/nl/msdn/community/columns/desmet/httphandler. mspx Regards, Steven Cheng Microsoft Online Support Get Secure! www.microsoft.com/security (This posting is provided "AS IS", with no warranties, and confers no rights.) -------------------- | From: "Bruce Barker" <brubar_nospamplease_@safeco.com> <uHktMd$BGHA.***@TK2MSFTNGP15.phx.gbl> | References: <E34D203A-31AB-4B55-9D90-0E31C4B40***@microsoft.com> <73416E59-B5D2-4A18-AD06-2437E5ED6***@microsoft.com> | Subject: Re: Embedding an image in the html? microsoft.public.dotnet.framework.aspnet:366857| Date: Fri, 23 Dec 2005 12:57:19 -0800 | Lines: 52 | X-Priority: 3 | X-MSMail-Priority: Normal | X-Newsreader: Microsoft Outlook Express 6.00.2900.2180 | X-MIMEOLE: Produced By Microsoft MimeOLE V6.00.2900.2180 | X-RFC2646: Format=Flowed; Original | Message-ID: <#n6f3NACGHA.3***@TK2MSFTNGP14.phx.gbl> | Newsgroups: microsoft.public.dotnet.framework.aspnet | NNTP-Posting-Host: rdcsd1.safeco.com 12.144.134.2 | Path: TK2MSFTNGXA02.phx.gbl!TK2MSFTNGP08.phx.gbl!TK2MSFTNGP14.phx.gbl | Xref: TK2MSFTNGXA02.phx.gbl Show quoteHide quote | X-Tomcat-NG: microsoft.public.dotnet.framework.aspnet | | i believe these are the correct versions | | opera 7.2 + | safari 1.2 + | firefox 1.0 + | mozilla (2003+) | | -- bruce (sqlwork.com) | | "David Thielen" <thielen@nospam.nospam> wrote in message | news:73416E59-B5D2-4A18-AD06-2437E5ED6868@microsoft.com... | > Oh wow - this is great.
