The Localist calendar cropper at it’s largest is 200×150 (4:3). We don’t publish the cropper dimensions on the event form because it ends up being more confusing for most users. They try to pre-crop images to match the “optimal” dimensions when there’s really no optimal. We don’t discriminate on size (by design!) and photo uploads should be treated like Facebook: the bigger, the better.
You can always adjust the cropping of the photo thumbnail afterwards if our auto-cropper doesn’t do it properly. Plus, while a cropped version of the picture is displayed initially, if you select the photo on the event details page then the entire image will come forward. The most common use we’ve seen of this is the top of a flyer image being displayed, but then when clicked the entire document is visible.
