id1 = " + idtxt.Text + "
Image1.ImageUrl = "~/photos/" + ID + ".jpg"
End If

I have a page which displays details and a pictures of employees. The details are stored in a SQL database and the images are on the server. How can I set a default Image to display (e.g. an Image saying "Awaiting Image") if an employee picture is missing?
I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.

How to display No Match Found when there is no data with the entered initials.
Ex: zz
Output No Match Found
i have added an new chart (data from acces database, looks like that:
1 2
123 123
333 222 etc).
No errors, no exceptions, but i realy cant see image ;-)
when Im trying to righht-click on chart in my browser and choose "show image" i get :
System.ArgumentException: The image is not found.
I have a problem with my chart image not refreshing and I narrowed it down to the fact that there's an unrelated image that according to MS VS2005 IDE, that the image file is not found... BUT..when I run/debug it... it displays properly.The image is right in the root of the aspx directory so it is not in any folder.<img src="right-thumb.png"> // this works but ide shows error and causes chart to have update problemi get an error in the IDE file is not found. however, if I display a FULL PATH, the problem goes away. WHY? i don't want to display the whole path because i don't want public users to see the server file location.
<img src="c:webapplication
ight-thumb.png"> // this works for everything
i also tried
<asp:image runat="server" id="Image2" ImageUrl="~
ight-thumb.png" />
and that too also has a problem! It underlines in red and says teh file is not there, but when i debug, of course it works and the image loads....
I'm using the following JavaScript function to hide images on my webpage in the event that the source image is not found:
function Image_OnError(image) {
image.onerror = "";
image.style.visibility = "hidden";
return true;
}
I add the following attribute to my images which calls the above method in the event of an error onerror="Image_OnError(this);".
The problem is that I need to do the same for <input type="image" /> elements but can't figure out how to do this as the input element doesn't appear to have an OnError event. I could just include an extra image with the same src value as the input and then modify the visibility of the input element on the image's OnError event, but this seems a bit messy.
Do you think the following one is best for adjusting Contrast level? In fact, I would like to get the same/close perfromance for adjusting contrast as found in Photoshop.

{
Value = (100.0f + Value) / 100.0f;

View 1 RepliesI have very basic knowledge of ASP.net. I am using following script to resize and image, but the problem is it increases the disk volume of resized image to almost 4 times or original image.
Example:
Original Image: 1024 x 769px and Disk space: 135 KB
Resized Image: 600 x 380px and Disk space: 825KB
Notice resized image becomes 825KB.
