[Plugin: NextGEN Gallery] [Plugin: Next Gen Gallery] Error when uploading

Hello All,

I have just installed WordPress with NextGEN, everything seems to works fine (I’ve manage to create a gallery and display it on the home page) but I cannot upload any pictures.

Every time I try (no matter what method I use to do it), my page come with a lot of error.

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg: JPEG library reports unrecoverable error: in /home/wp-content/plugins/nextgen-gallery/lib/thumbnail.inc.php on line 183

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: '/home/wp-content/gallery/news/alsace-jan-2008.jpg' is not a valid JPEG file in /home/wp-content/plugins/nextgen-gallery/lib/thumbnail.inc.php on line 183

I also have the following error message:
Warning: getimagesize() [function.getimagesize]: Read error! in /home/wp-content/plugins/nextgen-gallery/lib/nggmeta.lib.php on line 37
