Done!
Sorry for my last post. It were photos from the photograph. Here is my final working code. Don't forget to include the Lightbox-files!
#<?
//new fixes
// 12 May - missing </tr> in childgalleries in some cases (compliance error)
// handle alternate charsets
//
// etogal version 1.1 beta 3
// Fixes
// 14/04/06: MySQL 3.x compatibility: Join replaced by Left Join
// 29/04/06: 'Save Changes' string corrected for internationalisation
// 6 May : added prefix of EG to class names to avoid conflicts (EGthumbnail and EGimageview)
// 7 may : fix descriptions handling in is_target display (contributed by doze)
// generate URLs using makeURL (tested with FURLs)
//
// Additions
// 29/04/06:
// quality low, medium or high (low is the original Etogal setting, high mikef's improved quality)
// delete 0 or 1 (0=only administrators can delete images)
// display additional option of 'none' gives no image display, only manage button or management functions (when valid)
//
// this version retains the EtoGal 1.0 database table structure
// ----- Setting(s) ------
// Path where the galleries will be stored (you have to create it and make it writeable!)
