Clean your Gallery 2 ImageBlockCacheMap table regularly

Supposedly, Gallery 2 has a process to clean this table periodically (through Cron, which you should always configure), but apparently sometimes this doesn't get to execute correctly. As a result, the rest of the cleanup will happen but this stable might not get cleaned, leading you to millions of rows of purely useless years-old cache junk. Fix it manually by issuing a "TRUNCATE [prefix]_ImageBlockCacheMap;" in your database, or install a more recent version of Gallery, or something like that, but make sure you always keep an eye on its size.

Gallery 2.3 not translating

Just in case you would fall upon this issue as well, Gallery2 requires the corresponding language-specific locales to be installed on the system (it depends on them to show the matching translated terms). The code to do that (and to debug it) is located (in Gallery 2.3) on line 330 of modules/core/classs/GalleryTranslator.class. We hope it helps you a little.

Fixes for Gallery 2 French translation in module 'core'

After years using G2, I finally fixed the fr.po for core module and submitted it to latest registered French translator of Gallery2 several weeks again. After review, he encoded the following tracker on SF.net for everybody to benefit from it, even if no G2 update is ever published again:
https://sourceforge.net/tracker/?func=detail&aid=2846783&group_id=7130&atid=582564

As G2 is using gettext, updating it it fairly easy.

Enjoy!

Java Applet Uploader bug in Gallery 2 + Firefox 3.0

This is a bug we've seen but have been unable to explain so far... for several people, all the Java-based Gallery 2 uploaders applets and apps are crashing the Firefox browser or putting it in an unstable state, preventing us from uploading pictures. Apache doesn't log anything wierd. The Java console isn't very eloquent (but it reports a few exceptions), but the browser doesn't get to show the applications that allow uploading files this way. There is, however, a solution, which is to have a *clean* Firefox getting to the uploader pages.
