I feel like this is a very simple fix, but it has been a long week and my brain is not working! I am setting up an album and the thumbnail for each gallery is taken from a thumbnail within the actual gallery, which has been set to a certain size using the nextgen resize thumbnail function. What I need to do is have larger thumbnails appear in the album (to click INTO each gallery), but still keep the smaller thumbnail size within each gallery. Does that make sense?
Any advice would be greatly appreciated.
