I have just added 14 free to use (basically copyright free) images that have been optimized for use on websites as header images for WordPress templates that use pictures at the top of the theme. You can find the 14 header images on our main website under Free WordPress Header Images.
I stopped at the east end of Loch Watten today and photographed one of the several swans that live on the loch. The sun was shinning and the reflection on the water may either enhance the picture or distract from it, your choice. The loch is not yet open for trout fishing so there are no boats on the loch and the swans have the loch to themselves.
Below are a few images of photographs run through computer software to generate computer art images and enhanced HDR pictures. It obviously does not compete with a proper artist or a great photographer, yet you can take pictures from over a decade ago using a low cost digital camera and turn them into something interesting and attractive. Software such as Paintshop Pro has built in filters that allow you to create artist affects with you photographs and the software does not cost a lot.
