Function problems when trying to upload image

[artenman_6845]

Fatal error: Call to undefined function: imagecreatefromjpeg() in /home/*****/public_html/reviewpost/image-inc.php on line 103

This happened after I upgraded.

What is the filename? Is it other than jpg? sounds to me as if the program is reporting trouble in that the image is not named or being uploaded with an extention that the file header is saying it is.

I created the JPG myself, and I don't know if it's ReviewPost or what. I got that error with GD1 or GD2, when I switch to ImageMagick I get a different error:

Error creating thumbnail! Error code: 127

Command: "" -size 80x80 -quality 70 -geometry 80x80 /home/******/public_html/productreviews/data/30/1108hijackpro2icon-thumb.jpg

Can anybody please tell me what the problem is? All libraries are installed properly according to my host.

You didn't set a path to mogrify in your config-inc.php - it's blank.
