I've uploaded custom images (via SecureWebDisk) to the correct images/header folder -- no spaces in the file names or directories, and all are jpgs of roughly the same small filesize as the original images. The images display fine, but the rotation rotates through a period of white that, when you view the page source, are hidden copies of the new images -- see below. For example, one original image is greenGirlSm.jpg, and the hidden phantom copy is ._greenGirlSm.jpg.
When I view the hidden files (on my mac) they do not appear in the images/header folder and the Finder search function can't find them.
I've tried deleting, re-uploading and renaming the image files but it hasn't gotten rid of the phantom images.
Anyone have any suggestions? I don't know how they're being created or where they are to delete.
