reload current image

[Olivier R-D <o r-d laposte net>]

Hi,
I have written s small python plugin. that changes the iptc tags of the 
current image. unfortunately it seems that changing the image file also 
makes eog loose reference to the current image so when I click next it 
displays the first image in the current directory instead of the next one.
How can I force eog to reload a specific image or better avoid that eog 
   loses its reference to the current image ?
Thank you
