Most thumbs for videos won't show

[Mimer]

I've made thumbs for my videos, uploaded videos and thumbs in same dir with CuteFTP 8 Pro, and batch added the files.
Only a few af the thumbs are showing:

Any one?

OK, no one.
I'll rephrase the question in another thread.
You can close this thread.

Probably caused by the upper case filename extensions.

Problem solved.
My thumbs extension were lowercase and videofiles extension uppercase.
Every thing works perfect now.
Thanks for all your support Stramm and Nibbler.
