Yes there is anything beside the image editing feature, the dynamic 
resizing feature ;)

Thats means if you upload an image a image the image will displayed in a 
other size as the original.
For example you upload a image into your gallery with the size of 
800x600 Pixel and you have a look to your gallery you thumbs. The thumbs 
are resized images of your original image. When you now click to an 
image the images opens with, e.g 450x... Pixel. Thats also a resized 
image of your orginal image.

To prevent "image-resizing-attacks" you have to define all posible 
dyn-image-sizes in your admin-area.

How to do that?

- login ;)
- use bookmars in the right upper corner and select "site-options"
- in the bottom of the opened page you will find "image_allowed_sizes"-field
- there you can define your preferred images sizes


You also can use the dynamic-image-size-feature outside of the gallery 
in every xsl-file.


For example use this in a xsl-file:

<img 
href="http://your-url.com/dynimages/100/files/path-to-your-image/your-image.jpg" 
/>

100 = the preferred image size for the above example.

You mean in your gallery???

Edit your gallery.xsl file

there you will find the to Parameterdefinitions:


     <xsl:param name="thumbWidth" select="100"/>
     <xsl:param name="largeWidth" select="480"/>

the first one is for the thumbnail size and the second one for the 
"large" image.

If you edit this parameter don't forget to enable your new size in the 
admin area.

I'm not sure if this was your question. If not just ask again or someone 
else will give you the rigth answer ;)
