Oh my goodness.. I am EXHAUSTED!!! FINALLY decided to fix my NGG stylesheet ONCE AND FOR ALL to address two things I see folks ask about ALL THE DAGGONE TIME.. Centering the FLASH slideshow and centering the thumbnail images when displaying a gallery..
It took a while to find an answer that LOOKED correct (versus some of the guesses I saw posted)
This post: http://wordpress.org/support/topic/plugin-nextgen-gallery-center-thumbnails?replies=6 (in particular all the responses from rw79 were SUPER helpful in getting the thumbnails centering correctly. (I knew rw79 was on the right track when I saw their solution for IE7/IE8 compatibility)
I downloaded rw79's stylesheet and incorporated the suggested changes into my stylsheet. (I used the file comparison program Beyond Compare to clearly see the changes needed and where they should go. This is because rw79 had other modifications in their stylesheet which I did not need/want) and FINALLY I got centered thumbnails that works in ALL browsers (except IE7/IE8 of course **LOL**)
As for centering the Flash slideshow, it turns out that there is something missing from the default NGG stylesheet.. Find the section headed:
/* ----------- Slideshow -------------*/
and add the following:
/* Required to center the Flash slideshow */
margin: 0 auto;
and the FLASH slideshow will now center correctly. This change is NOT required if you are using the JQuery slideshow. (at least not in my experience)
I hope this will help save someone some searching.. Gonna add some tags to make this post easy to find..
