NextGEN Gallery, Risize Image Browser

I need to display the image sizes with a smaller width and height than the default. I have tried the many variations of the resize option, but have never seen any impact. The images remain too large for the page and visitors must scroll down in order to get to the previous/next links. I’ve searched many posts and this seems to be a universal problem, but then again, many of the posts are over a year old. The only solution I’ve found is to edit the style sheet. That seems kludgy to me, plus portrait orientations still require vertical scrolling unless I set the width percentage very small.

Given the importance of this functionality, I can’t believe there isn’t an easy solution. I’ve just been unable to find it.

I’d appreciate any guidance on this issue.

Thanks,
Andrew
