An image should be of adequate resolution, appropriate size and aspect ratio. Note that smaller images become grainy if manually stretched to a larger size.
Higher contrast images are more easily viewed for those with low vision or accessibility needs.
Use:
Authentic imagery such as City staff in action, Toronto neighbourhoods, City events, etc.
High resolution images
City-owned photos; ensure copyright permissions
Images of people that reflect Toronto’s diversity

Montage images
Multiple images as a grid
Monochromatically coloured photographs except historical black and white photography
