Some of the ways digital images can be stored and transferred and manipulated using other communications technology is through the internet, computers and USBs. Images can be downloaded from a digital camera onto a hard drive, such as a computer. From here the images can be altered by a number of programmes on a computer. This adapted image is then uploaded to the internet where millions of people can view it. Most people upload images onto websites such as, facebook, bebo, blogs, and myspace. These websites have security settings that the user can alter to suit them, for example some people wish to ensure that no one else can view their photos except for themselves and friends. On the other case a number of people up load the images in which anyone else can access the image and use it in their own way.
There are a number of ethical issues that come up when transferring digital images. ...
Digital images are being used in Occupational therapy (OT) practice for a number of reasons. Some therapist use digital images as analysing a client. An example of this is videoing a kitchen assessment and then going back to it to analyse in greater detail. Digital images can be used in presentations that OTs may put on especially in powerpoint presentations. ...

A digital zoom is linked to the pixel count. This means when the image is enlarged or cropped the quality of the picture is poor as the pixel count changes.
Optical zoom’s quality does not change when enlarged. So with the optical zoom the pixel count remains the same.
Mega Pixel is one million pixels. Mega pixels are not only in digital cameras but are also used in the number of image sensor elements of digital cameras or the number of display elements of digital displays.
