Is there a way to batch upload into 1 particular folder all the time (once the image is processed, it deletes itself so the folder remains empty) rather than having to make a new folder each time? And when you you make a folder and batch upload, this folder will always be use to reference the images?
that's not the way how batch uploading is working. But you always can FTP into the same folder (however it's not recommended). Coppermine recognizes the new images and will just batch add these.
