G2 Filter and exactsize

System: Drupal 6.12 + Gallery2 (v2.3 core 1.3.0) + Gallery Module 6.x-1.0

The "exactsize" option it does not work with the G2 filter. For example: [G2:1234 exactsize=448] would have to show the image with a size of 448 pixel. The "exactsize" value it is omitted and use the default size in pixels of thumbnail in gallery album.

For example: http://tomashidalgo.nom.es/Image_no_resize_with_G2_filter_and_exactsize

The content node is:
Esto es una prueba de foto incluida con g2Image.[G2:90 class=g2image_centered exactsize=448]
The source code:
<img src="/albumdefotos/main.php?g2_view=core.DownloadItem&amp;g2_itemId=91&amp;g2_serialNumber=2&amp;g2_GALLERYSID=69f46d7ab337483abd3d0c7211b3af07" id="IFid1" class="ImageFrame_none" alt="al agua bebes" width="114" height="150">

Over Drupal 5.18 + Gallery 2 (v2.3 core 1.3.0) + Gallery Module 5.x-2.2 work fine.

For example: http://www.padelalmeria.es/noticias/200906/hegemonia_total_de_orozcolato...

The content node is:
[G2:5079 class=g2image_centered exactsize=448]

The source code:
<img src="/albumdefotos/d/5079-1/DEPORTISTAS+PREMIADOS.JPG?g2_GALLERYSID=31ba0adbe74f7fe04475985817d20fbb" id="IFid1" class="ImageFrame_none" alt="DEPORTISTAS PREMIADOS" width="448" height="262">

Many thanks for you help and work.
