• Visual C# How to load images effectively ?

  Hi guys, In my program I want to view thumbnails.. But when the original image size goes up the program starts to freeze.. In my method I directly load the original image to an Image object and then using the GetThumbnail(....) method resize it and pass to another Image object. But it seems this is not an effective way !! Is there any idea, or trick or something else to increase this performance I am open to any advice.. Best regards I am barely new to this topic.. So can you wite the snippet on how to use Graphics.DrawImage() for getting image files I tried but all DrawImage() method overloads have at least one parameter to specify a location but I will directly put them in a pictureBox... Thanks ...Show All
