I am having the same problem…did you you fix it?
Adjusting the thumbnail size and position in “Manage Gallery->Edit Thumb” for a particular image where the error occurs resolved my issue.
Seems to be a bug, good luck
Regards
I think my problem is related, if not identical. Thumbnail images are not always appearing correctly lined up – close inspections shows some thumbs are about 1 pixel smaller and this affects the lining up of images on the line below. By going through and re-cropping the thumbs, all is fixed. But I don’t know how this happened in the first place.
If I inspect the thumb images I find they are all the same size, 74 pixels in my case – maybe it is related to the plug-in adding a border? Just a guess.
I had the same problem where pictures are not lined up properly. I deleated pictures and uploaded them again to gallery and it worked.A bit of a pain really and very time consuming.
I am having the same issue. See my gallery here – http://gabrieladias.com/dev/media/gallery/. These blank spaces have been such a pain! I’ve been working around it by shuffling images and reorganizing – seems to fix it 1 out of 3 times. We need a fix! 🙁
check css may be problem comes from css
I figured out a solution to my problem. The thumbnails that were creating problems for me were thumbnails that I had edited using NextGen’s “Edit Thumbnail” feature. I had re-cropped a few images and these images ended up saving at 164px wide while the rest of my thumbnails were 165px. I just re-cropped those thumbnails and no more blank spaces!
