I have had a gallery using gallery 3 for a while and it has been fine. I use the ftp option with a folder ‘gallery-images’ in the public-html folder.
Today I wanted to replace around 7 of the images, so I did so ensuring the new images used exactly the same filenames as the images being replaced. Once done I ftp’d the updated folder.
On the surface the gallery looks fine with new images in their correct places - matching the order of the ftp’d folder. However, when in lightbox mode using the arrows, images appear in the wrong order. The thumbnail strip along the bottom is also in a different order.
Any ideas what might be happening? http://thelodgetreehouse.co.uk/gallery
