what way can i make image bigger without losing quality?
Program Using: Photoshop 7
Problem: I have an image that is approx 10cm high with 300 res and I will need to be making a billboard with this image (approx 12 feet) Obviously the image is going to be distorted & pixely.
Question: Is there a way I can make the image gigantic with out loosing quality? Is there a plug-in or helpful trick used to take photos into life size images? -

In short – no. You can’t make something really sharp that isn’t already there. (Despite what every ‘police/spy’ TV program pretends to do…)
BUT, in practice. If you simply RESIZE the image Photoshop will automatically generate the extra pixels in a ‘smart’ function. It will look less ‘pixelated, but a bit softer / fuzzier.

Photozoom Pro may help but you are pushing it a bit. Goto http://www.benvista.com

Depends on the amount of detail already in the pic, probably not much at 10cm, however to improve that if it is sharp, print it on high quality photo paper and re scan at high res and however many % of the original size you can get away with.
works for me when I have to get photos up to A0 poster size. -
When in photoshop CS range, when using Image Size there is a resampling option, something like "bicubic smooth". I had some cracking results with that at well 10foot wide from reasonable photos

So just to follow on from this question, if for example I took a photo with a camera that had 10 megapixels, and then wanted to blow this photo up to be printed on a banner that was going to hang off the side of a building, say 30 metres in depth, how would this work? I don’t do wide format printing in house so not sure what happens to the images I supply others.

Paul – to ‘simplify’.
Say the picture has 300dpi at 300mm – if naturally expanded, it would only have 3dpi at 30m…HUGE pixels.
But in several programs including PS, you can resample the image when resizing – and apply a bi-cubic (smart) function as it re-renders the image. If you wanted a 30dpi image at 30m – it would generated the extra pixels based on what exists – smoothing & interpolating the new dots. The resulting image will be a file that could be nearly 100 times larger – but it will be smoother close up. It doesn’t really fix grainy pictures, but it does give the appearance of a smoother end result…which your brain interprets as being a better, clearer image as the pixel size is smaller.
