I have unforget it. If you have some free time, please take a look in the code and provide a simple patch to correct this ploblem. 

Gilles

I have to check some duplicated here. 
I'm quite sure this problem is present in image gallery/html export 
batchprocess and cd archive (with html index).
I don't know if we can have a patch for the incoming release, but
I'm studying the problem.

This bug is reported against 'imagesgallery'. This plugin has been replaced by a new plugin called 'HTMLExport', which is written completely from scratch. This bug report will now be closed.

Toma this bug I believe is present yet either in html export or 
in mpegecoder...

*** Bug 128035 has been marked as a duplicate of this bug. ***

according to bug #128035 (for IE)

Can someone check if it is really a problem for IE 
new html gallery plugin?
This plugin is changing the filename.ext into filename_ext.
That should work, the only thing I'm not sure is
as far as the page name concern e.g. filename_ext.jpeg.html,
so please check if it is a problem.
I found the problem reported here only for 
old html export plugin and cd archiver.
(about this last I'm going to release a patch soon)

Tested IMO the problem is only for cdarchive

SVN commit 547624 by anaselli:

Added webifyFileName (from html gallery)
and moved png file from old imagesgallery plugin
