In order to increase your photo size, I suggest you download and install Magic Photo Editor, FramePhotoEditor or Fotosizer. The last one is free of charge and once you launch it you need only to press the Add Image icon, to open your file and to change its size from the Resize Settings menu. Unfortunately, these application, will damage your photo quality, because they will not add any other pixels to your photo. They will only enlarge the existing ones. For this reason, I suggest you try Resize Pilot. Even if it is not free, you can use its trial version to increase the size of your file. Also, you can try online services like: Fix Picture, PicResize, or Fotor Photo Resizer.
