I trying to use the Storytelling Map Tour Template, but the images only come up in the thumbnail strip but not the large photo with caption. I have the same urls being referenced for both the thumbnails and the large photo.
Also, my map keeps losing the edits that I've saved to it like changing the symbols and configuring the pop-ups. I've updated and saved the map 3 times now and it keeps reverting back to default settings.
I have just followed your link using my iPad and the large photos seem to be working, although only about 50% of them, not sure if this is caused by incorrect URLs, it might be worth checking all your links are correct and accessible,
The only thing I could think why this may happen is that the thumbnails are created from the URL at the time you create the tour, if the URL changes after the tour has been created the thumbnail may still exist but the link to the full image does not.
It sounds like your links are corrupted, but just wanted to add that I've had luck creating a large and thumbnail version of my photos with the map tour. As taken from the map tour readme doc, the large photo should ideally be 1000x750 pixels, and the thumbnail should be 140x93. I just cropped my photos by using a 10x7.5/3x2 ratio and resized in photoshop. I think there is quite a bit of wiggle room for sizes, but this ensures your photos will look good on a variety of monitor sizes. Good luck!
So for whatever reason, my Locations.csv gets corrupted online and I have to reload the same table every so often. This may explain why my camera symbols will randomly change back to the default orange dot. At least now, I know how to look at the table and see if my urls are corrupted. Thanks everyone.
