There is indeed a default max size for image scaling, which is 1500 for 
either width or heigth.

To change this, you have to change the configuration of the image loader 
in the opencms-vfs.xml.

Replace the

<loader class="org.opencms.loader.CmsImageLoader">
<param name="image.scaling.enabled">true</param>		
</loader>		

with

<loader class="org.opencms.loader.CmsImageLoader">
<param name="image.scaling.enabled">true</param>
<param name="image.scaling.maxsize">2500</param>
</loader>		

This would set the max size to 2500.
Do not forget to restart your OpenCms after you made the changes to the 
configuration.
