Updated the dataset view for image functionality.
The Image view now displayes the images in each individual set, enabling multi sets of images or previews on a page to be used by the ImageView.
Functionality also added includes:
- A Play and Stop, to cycle throught the set.
- Resizing of the widget based upon the image size - This could be changed in the future to prevent moving of buttons (functionality).
- Ability to show image properties such as Timestamps, Filesize and Dimensions (of preview image, not the full size. a TODO for future updates).
