How are images sorted?
By filename
Images are sorted by filename. At this time there is no way to re-sort the images by other criteria. We recommend naming files in the order you want them to appear in the slideshow.
Manual sorting
Once the images are uploaded to SmartSlides, you can manually sort them in the Slideshow Editor window by dragging and dropping them to the desired position, and even moving them to a different segment if you are using more than one song.
