That is impossible to do, but you can minimize damaging the resolution by doing something called upsampling.

Any enlargement of a bitmap involves creating pixels from existing data. If you enlarge a picture to 200%, each pixel in the original has to become 4 pixels in the enlargement. The simple way is to simply make 4 pixels of the same colour as the one in the original. Smarter methods take into account the colours of neighbouring pixels, so the enlarged picture has a 'smoother' look to it, though it cannot contain any information that wasn't in the original picture (if an object in the original was smaller than one pixel, the enlargement cannot show the object any better than the original picture).

So enlargement doesn't damage resolution but it can't improve it either. The link that Jupiter provided above has a good example of how 'upsampling' changes a small, pixellated image to a larger, smoother one. The article also suggests that better results are obtained by increasing the size in several small steps rather than in one go.

If it is at a high enough resolution to start out, then you will be able to enlarge it to full size without looking pixelated. But if you took the picture on a lower resolution you won't be able to get it too big. If it's something that you took on you camera, then you should start setting you resolution to high. If it's a graphic from the internet, then you might want to find another one.

If you have a good printer you can print the image and then scan it in at a higher resolution. This will not give you more detail, but it will help get a higher resolution since the ink/toner blending when it prints will spread the pixel colors out.

Regardless of what method you use, the picture will get grainier as the size increases.
