Optimize form (containing .png backgrounds) loading in C#

My problem is that I have an application developed in C# and before adding .png backgrounds all the forms are loading smoothly. After adding the backgrounds, the forms are loading much more difficult than before.

What can I possibly do in order to avoid the slow loading of the forms?

Thanks!

Png format is faster than jpg and bmp.but you must load them at application startup.

Image Backgrund1 = Image.FromFile(@"MyFile1.png");
...
..
.

And in the load event set them to background;

this.BackgroundImage = Background1

Did you test it?

Also you can compress your images with some software such as photoshop -> Save for Web. It

You could add a timer to your form with a delay. Then load the PNGs in the tick event (as well as disabling the timer). That way the form would appear straight-away, but take a few seconds to show the PNG.

You could also try loading the PNGs in the Form_Shown event, although i'm not sure if that occurs after the GUI is displayed.

A final option could be, if appropriate, to load the forms before they're needed.
