I have an image in one of my project folders:
Lets say its in: ~/App_Themes/Default/images/SomeImage.png

I want to load this image into a System.Drawing.Image, how do I do that?

If I try using the FromFile method of the Image class:
Image img = Image.FromFile("~/App_Themes/Default/images/SomeImage.png", true);

I get a "FileNotFoundException".
I have read some suggesting to store the image into the Server but that's not an option. Is there any way to load this into the Image?

Try using the server.mapPath() method to point to the file location if this is a web project.
This will look for the folder and file in relation to its physical location to the root folder

Thanks for the reply but it didn't work, I still get the same FileNotFoundException exception.

Can you locate the image using the physical path? i.e. create a image link on your page where the src points to the image? If you can't then you may need to verify the image location and name.

I can locate the image using the physical path but for some resaon when I use the Image.FromFile method an Exception occurs.
