Since the installation of Zenphoto (installed myself) I find that Admin navigation as well as gallery navigation are extremely slow.
I've worked to keep the files I've uploaded from being very big, the largest are around 800 pixels on the longest side.

I have 5 albums with a total of 70 images. I'm really not sure why it would be running so slowly and after searching this forum I didn't quite see anything exactly relative to my situation.

Any input would be greatly appreciated.

Gallery: http://www.visualechoes.net
Zenphoto version 1.2.9 [5088] (Official Build)
Current gallery theme: zpgalleriffic (actual album theme is default)
PHP version: 5.2.12
MySQL version: 5.0.83

Let me know if I need to provide any other information.

Thank you!

Seems to me that your server slows down on processing images, in which case the only thing I can suggest would be to try pre-caching your site's images. There is a utility for this on the admin overview. Other than that, I didn't notice much slowdown on my end.

One other thing I noticed is that your debug log contains quite a few of these messages:

`
Backtrace: Bad filename suffix in newImage(advanced.html)
newImage called
from zp_load_image (functions-controller.php [342])
from zp_load_request (functions-controller.php [435])
from require_once (controller.php [43])
from index.php [23]
`
You may want to try upgrading to 1.3.0 (or wait for 1.3.1) and updating the parts of zpgallerific that your theme uses accordingly. That might get rid of the above problem.

Okay, thanks so much I really appreciate it!

More specifically, you either have HTML files in your albums and do not have the text object plugin enabled or the theme is doing something wrong. The error that kagutsuchi mentions is saying that Zenphoto was asked to process an "image" with the suffix ".html" which, of course, is not a valid image. It can be handled only by the text object plugin.
