Dimensions of a picture

I have a problem with the following fie :
\useexternalfigure[fig1][Mouette1]%1600x1200
\useexternalfigure[fig2][Mouette2]%1024x768

\starttext
%the following line gives an error :
%Error: pdfetex.exe (file ./Mouette1.jpg): reading JPEG image failed
%\externalfigure[fig1]

%the following lines runs very well 
\page
\externalfigure[fig2]
\stoptext

Is there a limitation of the dimensions of a picture ?
Or another problem ?
Thank you

It seems probable that your JPEG file is broken, there is no
size limit for JPEG images, but there are some checks to make
sure that the file is 'valid ', and your image failed one of
those checks. There is nothing more I can say without the actual
image file.

Greetings, Taco

There are several command-line utilities for checking image files. The 
ImageMagick suite has a program called 'identify,' which will give you 
lots of information (probably more than you want!):

     identify -verbose <image_file>

If you're running Linux, ImageMagick is available for just about any 
distribution, and may already be installed on your system. I think you 
can get a version for Windows, too; not sure about MacOS.

If the file is broken, 'identify' will tell you so. Otherwise, post the 
output of the command to the list, and hopefully someone will be able to 
tell you if there's something unusual about your file that makes it 
incompatible with pdefetex.
