Rather than just not render certain images when the "daytime photos only" and "exact images only" boxes are checked, it might be more useful to change the TS plot so it doesn't render markers at data points with nighttime or non-exact images. Especially with the non-exact images, you might end up having to click through a lot of data points before you find a data point with an image. This would make those points of interest easier to find.
