The previous file could not be placed. (Big prublem)

[Gin]

I have prublem!

i uploaded file *.jpg

script shown:

The previous file could not be placed.
You have successfully placed all the files.
Cuntinue.

I know:
script load pic by HTTP then move it from /tmp/*this_file* to /my_edit_dir/*tmpHTTP_name*.jpg
so when i copy this file by FTP-client - this file isn't a picture!!!!!!!!
(when i load pics by FTP to server - there isn't any prublem with adding pics  to base.)
and then i can't add this picture to my base.
i use
Coppermine Photo Gallery v1.3.2
GD-lib2.0
Image Magic 6 (or something like this)

Thanx for help.
