When I disable the crop function in the plugin options it's going ok when the thumbs are all landscape, but when they are mixed landscape and portrait then I have a problem.
To see what happens look at following page http://www.avdsteltphotography.com/macro/DSC_3848.jpg.php
Greetings Arjan
Give tonight's nightly a try. Note that you need to update your theme's css as the paged thumbs nav now has also separate ids for both the active and the inactive "next thumbs" links (pagedthumbs_nextdisabled/prevdisabled) in case some theme design need that to be show (sometimes looks cleaner). I guess you know you can easily hide them via css's visibility: hidden again.
