Why do I have to upload a zip file of multiple images? Why can’t I instead upload an entire folder?
Because of the way browsers work. For a number of reasons, mainly related to security, browsers can’t open and read folders on your hard drive – this is why most photosharing sites (such as Flickr) require you to install an upload software tool on your computer. You can point a browser to individual files though. The easiest way to upload multiple images to MTBGuru is to put them in a single zip archive file that you upload just like you would an individual image. It will be unpacked and a thumbnail gallery will be displayed below the ride map. You could also upload a sequence of single images, but that’s the more tedious route. We may build a better upload tool in the future, but we think the zip file solution is a fairly painless one.
