Premature end of JPEG file

Hi,

I'm porting GD to javascript in my wxJavaScript program. Everything 
works fine, except for loading jpeg images. When I load it with 
gdImageCreateFromJpeg, I get the following error:

21:54:41: wxJS: Running Scriptfile 
c:\development\wxjs\wxJS2\samples\gd\load.js
Premature end of JPEG file
gd-jpeg: JPEG library reports unrecoverable error: Invalid JPEG file 
structure:
missing SOS marker
21:54:44: Error: wxJS: c:\development\wxjs\wxJS2\samples\gd\load.js(1) : 
Class ImageJPEG can't be constructed
21:54:44: Error: Evaluating script failed

I can open the Jpg-file with IrfanView without any problem. The image is 
created with gdImageJpeg.

Franky.
