I just installed 1.2x Pro, and the basics are working...resize, lytebox, slide show, etc.
I can't control the image order, though. I am trying alphabetical and alphabetical (case insensitive). The pictures are in a specific sequence. The names are like babytobig00sm.jpg through babytobig11sm.jpg
I even have a labels.txt file with descriptions. My opinion is that the gallery should follow the order of the labels.txt file, if there is one. That would enable custom ordering.
My galleries are at
nutreeent.com/site/index.php?option=com_content&task=blogcategory&id=13&Itemid=27
specifically the one called Nurturing New Trees
This is all problematic, because I am sure that there are server and client caching issues. When certain settings, like image order, are changed, there should probably be some procedure to clear the server cache, and to maybe remind the viewer to reload the page or something...
There are some issues here that are marring what seems to be an otherwise great program.
