This is not possible.When you are increasing the size of the picture, the pixel size of that image is also increasing.This makes the picture unclear.This is called the pixalation.Its possible when you start with a good quality image.Later you can't change the quality of the picture.

If you are looking for solution with Photoshop then it is useless because that's not at all possible. However, if you want then you can test some other applications which can help you with good solutions.

What kind of image are you working with? Increasing the size of certain kinds of images is possible, but requires a lot of time and effort to do.

the pixel size doesn't increase, the pixel count does.

the rule of thumb is you can't scale up. period. you can scale down from a larger image, because to scale down, you take information (pixels) away. the original information is reorganized, smoothed out and the excess is thrown away. scaling up means you have to fill in information, which means you're creating holes and trying to fill them in based on what's around them. since the program doesn't have eyes and can't interpret the scene, it can't accurately fill in the information - a shrunken shirt of mickey mouse doesn't all of a sudden become mickey, it becomes larges blotches of grey, yellow and red, because at it's small state, that's all PS thinks it is.

the only way to go up is to recreate, aka redraw.
