Have you changed any settings in the image module, like the default size of previews and thumbnails? You could try reverting to defaults and see what happens. Also, there's something about whether it uses Image magic or some other image toolkit (?) - you could check that. And also what are the allowed file extensions in your file settings.

From what I've heard, some people prefer using CCK with image fields to using the image module, but I haven't tried it.

Hi all,

maybe I'm stupid, but I'm having heavy problems using the Image module
in Drupal 5.1, GD 2.0.8, Image module 5.x-1.3.

I never can't create a new Image node with different error
messages (not beeing useful at all). E.g.:

  1) a .jpg out of Photoshop, dimensions 821x376, size 18 KB gives me
     this error message:

       Unable to create scaled Preview image

     See the screenshot at:

       http://georg-rehfeld.de/test/drupal_image_problem_1.jpg

     The strange thing is, that the preview actually _was_ created,
     as can be seen in the screen shot.

  2) a .png file out of Photoshop, dimensions 570x457, size 41 KB gives
     me another error:

       You must upload an image.

     Shot at:

       http://georg-rehfeld.de/test/drupal_image_problem_2.jpg

     Again, the image I had choosen, _was_ actually uploaded and
     obviously processed (thumbnail generated) ... and believe me,
     that red marked field wasn't empty, when I pressed the 'Preview'
     button. Besides, the 'Attachments' section is empty.

     Same with a .gif file, dimensions 157x157, size 6 KB.

What am I missing? Most obviously I have done something wrong, because
the image module seems to be far away from alpha/beta and others seem
to be able to use it.

Any suggestions are very welcome. If you need more information to help,
I'll provide it!

Thanks in advance,
Georg
