Hey @shanr , there are many different kinds of images in Blender, so I’ll need a bit more info in order to help. Are you referring to a background image in the viewport like in the video above, or an image texture on a mesh? Which settings are you looking to change? What result are you getting now and what result are you hoping to get?
I realize learning Blender can be frustrating at times, but it’s definitely worth it! I’m happy to help, but I can only do so if I know what about images or their settings that you need help with. Please be as specific about your issue as possible and answer each of the three questions above so that I can know how to help.
