Jan 18, 2011I have a database which signature images. Images are saved in binary.
I want to retrieve the image and display in an image control. I am kinda new to ASP and what seemed so simple has suddenly become a real problem.
The at the botom is how I would do it on a winform. Unfortunately I have no picturebox control in .asp. So how do I get the image stream into image1.imageurl?

Web Forms :: Displaying An Image Within An Image Control On A Website From A SQL Database?
Oct 19, 2010I am working on a website, using C# with a SQL backend. I'm using the Varbinary data type to store my images because the Image data type is eventually going away. I got the images into the DB and can pull them back out to display on the website. My question is how can I put the images from the DB into an Image control on the website? The images will be different sizes, so I need to keep them confined in one space on the site. I also need to randomly display the images, one at a time, on the website. The user needs to be able to hit the Next button to see the next image when they are ready. The user will only view the images, not make any changes and send data back to the DB.
Since the image will be confined within the image control, how can I allow the user to click on the image and open in a new window? The image needs to be bigger to allow the user to see more detail. Or would it be easier to allow the user to zoom in on the image within the current window?I am using VWD Express, C# 2010 Express & SQL 2005 Express.

View 3 RepliesRead Binary Column In Database Into Image On Asp Page - Code Doesn't Work?
Mar 11, 2010I want to read from database where I've stored a image in binary field and display a image.
while (reader.Read())
{
byte[] imgarr = (byte[])reader["file"];
Stream s = new MemoryStream(imgarr);
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
Graphics g = Graphics.FromImage(image);
g.DrawImage(image, new Point(400, 10));
image.Save(Response.OutputStream, ImageFormat.Jpeg);
g.Dispose();
image.Dispose();
}
con.Close();
This piece of code doesn't work:
System.Drawing.Image image = System.Drawing.Image.FromStream(s);
I tried the code from this article. And I got the same mistake " the parameter is not valid ". Maybe I'm not aware of something, some setting in sql server or webconfig or sth else. Anyone else who has experience from fetching images from database? The parameter is not valid is the error message. db table contains data. What am I doing wrong?
