This page explains how to stream an image to the browser when it is generated from an ASP script using our csImageFile component.
Streaming an Image in ASP
It is an important technique that is not completely obvious at first. There can be complications with passing variables through the application and with debugging and we will address these issues in the next two pages. For example, if we have a web page containing some text and a dynamically generated image, the web page could have the following HTML code:. The code for “image.
NewImage, “FF”. The first three lines of code prevent the script from being cached. The csImageFile object is created and called “Image”. This example uses the full version of the component, the trial would use Server.
A new image is created which respoonse.binarywrite simply a red square, pixels across.
It is important to note that there is no text or HTML output in this script. There are no Response.

Write statements, no HTML tags and there is no attempt to redirect the page after it loads. None of these would be meaningful because the output of the script is a binary data stream containing a single GIF image and nothing else.
Any other characters would corrupt the image. If this script contains an error the server will send an HTML page to show the error message. This cannot be interpreted as an image by the browser so the browser will show an empty image marker. This makes debugging difficult but we will explain more in the next pages.
This buffers the output in smaller chunks of data rather than sending the entire image as a single block. This is a more efficient method of streaming large files and prevents the error that can be generated if Response. StreamToBrowser should be used for large images such as original sized photographs or multipage PDFs, but for smaller images it makes little or no difference.
