Help-Can't upload pictures

[crihan]

When I try to upload pictures, (ex: jpg extension, size 30k -max is 100k, user or admin mode), browse, continue, and in the next page with "Please place the files in albums at this time. You may also enter relevant information about each file now", in the left of this not apperar the picture (orphan like), after click continue I get the message:
"The previous file could not be placed.
You have successfully placed all the files."
Result: in the albums folder, in that album (10001) appear that jpg file but did not appear in the webpage and the server error log return this:
