Over lapping photos

When merging or overlapping photos it is important to try and keep the sizes of your photos similar. If you have taken your own on the same camera, with the same settings this should not be a problem.If you are using internet images you should check the resolution and size of the image, shown above. When choosing images from the internet, try to select images of similar size and resolution. If you need to adjust the size and resolution of the image, reduce the larger one to the same resolution and similar size ( click constrain proportions to ensure the image is reduced in the correct shape)
