Problems with Resigning Images:

I have developed a project in Umbraco cms and I want to display only one image on multiple pages with various sizes. In the image folder, I saved an image with a different size. For example,

TestImage_200x200.jpg, TestImage_400x400.jpg

but this is not a proper way.

I have found a solution to resize only a single image in different sizes. I have installed ImageProcessor in my application.

You can download ImageProcessor libraries via Nuget because its simplest and fastest way to install it.
