Sorry, no bug here You can see on your site that it works fine, as I just uploaded an image. You are just not doing it quite right. You have to upload image BEFORE you save the event. After you select the file, you must click the UPLOAD button. You will see the image load and display in the backend... if you don't, you won't see it on the frontend. If you just select the image without clicking Upload, then save the event, nothing is done with that image file.
