Error trying to build Thumbnails

[Guest Joyera]

I downloaded a bunch of pics via my FTP Client (as I have done in the past)

I have put them in the same folder as other pics already uploaded.

I went in to build the thumbnails and I get the following error messages:

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg, libjpeg: recoverable error: Premature end of JPEG file in /home/joyera/public_html/classes/gd/gd.inc.php on line 59

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: '/home/joyera/public_html/images/uploads/IMG_1100.JPG' is not a valid JPEG file in /home/joyera/public_html/classes/gd/gd.inc.php on line 59

Warning: imagecreatetruecolor() [function.imagecreatetruecolor]: Invalid image dimensions in /home/joyera/public_html/classes/gd/gd.inc.php on line 223

Warning: imagejpeg(): supplied argument is not a valid Image resource in /home/joyera/public_html/classes/gd/gd.inc.php on line 233

Warning: imagedestroy(): supplied argument is not a valid Image resource in /home/joyera/public_html/classes/gd/gd.inc.php on line 242

what am I doing wrong? I am completely useless when it comes to script, so any solutions in "complete idiot" format would be appreciated :(

I assume your url is http://www.joyera.com.au ?

I strongly suspect a corrupt upload/file (possibly from FTP transfer). Can you view the newly upload jpg (not the thumbnail?)

The transfer mode should be Binary for images.

(filename will be Case Sensitive - so has to match the original file)
