Pictures for any products uploaded not able to see

Jul 4, 2013 at 3:14 AM
I've just started to use NB_STORE Module and i did followed tutorial video.

I guess, everything i followed worked as the video showed, except photos.

I uploaded several times but it did not show up as the video clip showed.

Just the title of product showed up with "x in picture box". ( i attached the picture for your understanding)

but if i clicked the "x and title what i uploaded" it poped up and i can see the picture.

What should i do to fix this problem?

Pls help me out with this.
