After reading another thread there was a method posted up on changing a 72dpi image to 300dpi but required copying and pasting. There is a much simpler method than that. Firstly, open up your 72dpi image in Adobe Photoshop and then go to Image > Image Size.... You can see my original image is 27cm x 36cm but at 72dpi which is no good for printing. To change your image to a 300dpi resolution all you need to do is uncheck the Resample Image box and type in the new resolution, in this case 300dpi and click OK: Your image will decrease in print size, this one has gone down to 6.5cm x 8.6cm but it is now of print quality. The larger the pixel size of your 72dpi image the larger your final 300dpi image will be. A lot of free images from stock sites like SXC come as native 72dpi images and the above method will quickly convert them to usable print images without the need for copying and pasting into new 300dpi documents. I hope some folk find this useful. Col.
