Slow and cannot view full sized jpg

I got the software to along with the ravpower filehub RP-WD03 the hardware is fast when I access it using SAFARI. I can quickly download 9mb jpg and view them full sized, however when I use the filehub plus software the preview images download slowly, worse I am unable to view full sized images which is the main reason why I purchased the filehub. This app ruins what appears to be a good piece of hardware.
