Resolution

When we download our images, the resolution is normally set at 72 DPI (dots per inch - picture information) but when we do our final images we should set the DPI as 300 because it is the highest quality when we come to print - this means that all the information would be kept for the image, but if we only saved it at 72DPI and we changed the height/width of the image we would end up loosing a lot of the image information. When we change the DPI to 300 we need to change the size of image because it would automatically save the image as a very large file which would end up slowing down the computer or take up a lot of the space on the computer/memory stick.
