Getting a good photo gallery up in Word press is a NIGHTMARE.
Gallery2 is probably the only decent alternative.
However, it is ABOMINABLY slow to upload, and unless you’re using something FileZilla, you can actually *lose* files to the upload making the actual script impossible to use. You can imagine how frustrating it is to start searching for those files, then manually uploading it thereafter.
Also, getting some of the modules to work has been an abomination too.
1) I wanted to get publishXP to work so Anita can upload images easily. Turns OUT that it only works with certain modules ALREADY installed … in the 2.1 version. Fine. I upgrade to 2.1
2) THEN when I go to WPG2 plugin, I find out (PULLING HAIR OUT) that it only compatible with gallery 2.0(!).
Dilemma: publishxp very slick … but otherwise cannot integrate it with WP as a plug in which also is driving me batty.
What’s really surprising is that no one has created an easy-plug-in gallery for WP that works really well.
