getimagesize

Amigos já rodei quase todo o forum atraz de resolver um problema na função que verifica o tamanho da imagem, veja o seguinte erro que acontece quando faço o upload da imagem para meu servidor:

Warning: getimagesize(/public_html/meusite/pasta/admin/upload_imagens/pdil194046.jpg)

[function.getimagesize]: failed to open stream: No such file or directory

in /home/empresa/public_html/meusite/pasta/admin/thumbnail.php on line 80

Warning: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions

in /home/empresa/public_html/meusite/pasta/admin/thumbnail.php on line 100

I - Gostaria de saber se este erro é porque no php.ini não está habilitado no meu servidor que hospedo o site.

II - Gostaria de saber se isto pode ser um erro no código fonte da pagina, peguei este código na web para aprendizagem... veja o codigo do arquivo "thumbnail.php"
