To make sure that images are shown in the best quality on both the mobile and desktop site you need to upload images in a ratio of 3:2 so that they fill the space given to them.
The summary results pages show images at 224x149px and the property details page displays images in the main gallery at 656x437px.
We can accept images up to 1024px in width or height meaning that landscape images for example will be shown at a maximum 1024x683px. You don't have to worry about sizing images down - we can do that for you.
If you provide larger images it will show a link to 'enlarge' photos which shows your images off up to a max height or width.
