Following my previous post, where I investigated the performance impact of loading images in .NET application, I will conclude the discussion with optimization proposals.

Optimizing images usage in .NET – part 1
Using image is an integral part of GUI application but I have found very little resources on it's resource consumption and how I can optimize it. The goal of this post is exactly that, in part 1 I will show the performance impact and in part 2 I will propose an optimization.
I'm going to consider only the memory usage as CPU performance is generally insignificant.

Using T4 Templates for caching image resources
In my project I'm doing a lot of native UI rendering1, soon I will blog on why.
Naturally I have many images to render using DrawImage methods, that requires an Image instance.
There are couple of ways to load an image but the best2 and easies option is using a Resource File, just dragging and dropping the images into the resource designer will add the file to the project and generate a nice static property by the name of the file in the static class generated by the name of the resource file.
The problem is that each time image resource property is called a new image instance is created with the requested image, so if the same image is used in multiple places3 it will be loaded multiple times in memory4.
