Sure it works (click the images to see the original screen capture):
Now, is the pixelation of which you are complaining similar to what you see in the first of my zoomed images versus the second? That is simply a function of what, if any, interpolation you use when you zoom in by resizing the image with your image editor.
My first example uses simple pixel resizing. In other words, I just made each pixel three times its original size. This makes the pixels larger and, thus, the pixelation easier to see. It is the same effect you would get if you just move your eyeball closer to the original image.
My second example uses bicubic interpolation. It uses the values of the original pixels to calculate interpolated values for the new pixels that are inserted when the image is made larger, thus making the picture smoother.
There are many other interpolation methods as well that use different algorithms to approximate the values for the new pixels, including the aforementioned bicubic, bilinear, triangle, Bell, Mitchell, Hermite, Lanczos, et cetera methods. They vary in how fast they calculate and how smoothly they interpolate while still maintaining detail. I wouldn't worry about understanding all the differences. For the most part the results will look pretty similar as long as you use some form of interpolation and not just pixel resizing.
It looks like G@M3FR3@K used some sort of interpolation beyond simple pixel resizing when he made his zoomed images. Read the instructions for you image editor and you will find out how to use the different interpolation methods.
