I sometimes use the screenshot feature copied to clipboard to paste it quickly when I need it. I usually use that in Mail, however I always realize that the picture sent is really small in size (resolution). If a screenshot is taken at a resolution of 800x600, it is scaled down to 300x100 or something similar (just a rough example).
Is there a way I can keep the resolution of screenshots copied to clipboard 'exact' ? And prevent them from being scaled down ?
