When using the “Photo” option on my FVP 5000T to display photos from a USB drive I don’t seem to have any control over the order in which the images are displayed.
I’ve tried renaming from the original file numbers to a simple 001.jpg, 002.jpg, 003.jpg etc but they are being displayed on the Humax in a completely random.
Create your own by using a Video editing package or slide show creation software complete with music. Save it in mp4 Full-HD format and 16:9 aspect ratio and copy to a usb stick and connect it to a 4000/5000T USB port.
I suspect that both units simply get the folder contents and display them in that order. You could just try reformatting the USB drive and adding the files in one go or in desired sequence.
Graham’s suggestion is full proof, I just offer an explanation of why it may be so.
