KK, The reason for this is due to your phone not compressing the photos when sending to your computer. If taken with a digital camera and the camera has different sizing formats, that is why they open when used. Most cell phones dont have a sizing style format to choose from, thus leaving the photos as is. Something like that...Might not be worded right, but is the reason for this. When transferring from your digital camera to your computer, the images are in a compressed state and will open after you post. JPEG style images are just one example of this and can only be done when using a digital type camera. Im no tech when it comes to this, but do know a little bit about how this works.
