trouble adding new file to directory

[cocamax]

hello,
i checked in the post but i could not find the same problem, or maybe i did not look into the right section...  so here is my problem:
i tried today to add some new files into a new directory. But when i've selected the directory where my files are stored, it showed a red cross instead of the small pic as it did before or as it did with the other directories. Then, if i've selected a pic and i inserted it.. i got this message error:

Warning: getimagesize(): Unable to access albums/slobodan/thumb_DSCF0001_redimensionner.jpg in /var/www/free.fr/2/7/brassart.r/cpg132/include/picmgmt.inc.php on line 226

Warning: getimagesize(albums/slobodan/thumb_DSCF0001_redimensionner.jpg): failed to open stream: No such file or directory in /var/www/free.fr/2/7/brassart.r/cpg132/include/picmgmt.inc.php on line 226
Unable to create thumbnail or reduced size image.

i don't get why it does not work any more..
i hope it is clear...

i fixed the problem ... i just changed  the Method for resizing images.. it was image magic and now  i set it to gdversion 2.x..
i don't get why it worked before...
