Return Existing Graphic

[Jonathan Wood]

I know how to generate an image on the fly. But does anyone have an example
where I return an existing graphic instead of generating it?

I want to return one of several existing graphics images based on the
argument provided.

Thanks.

Where do the images exist? Database, files, something else?

I'll probably just store the images as files on the server.

I run some algorithm and want to return one of those images based on the
result of that algorithm.

Thanks.

If you are using an image handler to handle your images (wether generating
or not), then can't you do something like...

if (File.Exists("pathToImage"))
{
Response.Redirect("pathToImage");
}
else
{
generateimage;
}

Easy enough. I'll give that a try.

Thanks!

you may try and using the object
of type

System.Drawing.Image

oImg = oImg.FromFile(absolutePath)

and the same image can be displayed to the output screen.

Response.ContentType = "image/jpeg"

oImg.Save (Response.OutputStream, ImageFormat.Jpeg)

Thanks for the info. I'll look into that.
