Your venue gallery and workspace images should all be horizontal images.
The recommended pixel sizes for your images are listed below. If your images are vertical or a smaller resolution, they may look stretched or low quality on the LiquidSpace site.
Where possible, use full images. The LiquidSpace editor will help you crop a picture to the right size. If you choose to crop a small section of the photo, it could decrease the quality.
Logo: 300 x 300 (must be square)
