Software to compress jpg images without resize?

[Temi_D]

Hi all, I want to change the picture of my windows 7 welcome screen using the registry edit (Is there an easier way?). The problem is that the max image size allowed is 256KB and my monitor has a resolution of 1080p so I need to compress the images I want to use without resizing. Is there any software that does this? Thanks
