Copyright and image rights
If you have the copyright to something, this means you have the rights of ownership to a piece of work, in this case photography. It is very unusual for a photographer to assign copyright to a client, although they may grant a total buy out. This means that they are willing to let you use the images they capture for any use, forever, with no time restrictions, or additional fees whilst retaining copyright.
When reproduced, published or printed, all images must be credited with the correct copyright information, usually the name of the photographer and/or image library, for example:
© Tina Bloggs/Images Inc.
The copyright information can be printed on or next to the image itself or as a list at the back of a document, detailing the page number the copyright refers to.
Online, meta tags can be used to display copyright information, but it is not good practice to include it within Alt tags.
If you are commissioning photography it is important that you negotiate the rights for usage with the photographer before committing to any services. Once images have been shared through the network it is very hard to control their use. If you have agreed to only very limited rights to the images this will then expose the organisation to the risk of being sued for copyright infringement. It is always best to negotiate the widest possible rights for image use.
