Lightbox stopped lining up images in galleries as settings request

Hi there,

I encountered a problem with galleries created by Lighbox plugin recently. Previously it displayed images in accordance with settings, 3 photoes in a row, but a week or two ago it changed (maybe it happened earlier, but I noticed only recently). Most of the photoes are still displayed correctly, but sometimes it shows 1 image in a row, 2 in a row, while other images in the same gallery are still displayed correctly. Please see below links to pages where this problem appeared:

http://aida-style.com/best-of-april-collection/
http://aida-style.com/best-of-may-belly-dance-collection/

I have a lot a photoes on the site and most of them belong to galleries, and I can not understand the reason for this weird trouble. The height of the photoes is the same – one gallery contains images of the same height ( wight is more or less the same also).

Does anyone has any clue about this problem, and what is the solution?

Thank you in advance!
Alie
