I’ve been using the gallery\_behavior for a simple directory/file based  
gallery. Works well - but have a couple of questions that others may  
have  
already experienced…

1. Is there a way to control the image caching separately from the rest  
of  
the site? The default cache is 5 minutes and is quite short for an  
image  
gallery that has to generate the thumbnails on the fly. Just causes  
overhead and slowdowns. The temporary fix I have in place is to do  
longer  
sitewide cache - however not ideal for other parts of the site.

2. The auto resized images and thumbnails that are generated seem larger  
the  
expected, is there a quality switch to reduce the quality when resizing?  
A  
80x60 thumbnail shouldn’t be 20 KB, should it? Is the option to just  
change  
the thumbnails to GIFs versus PNG?

Hi,

I don’t think there is currently a way to individually change the cache  
timeout for certain requests, but I don’t see it to be very hard to  
implement in one of the future versions of either Radiant or the  
gallery\_plugin.

PNG might have been a bad choice and I should probably provide an option  
for JPEG and/or GIF. Also for the larger images JPEG is certainly a  
better  
choice since right now images seem to take forever to load.

I might be able to add those features sometime this week or over the  
weekend.

Cheers,
