I think this is  CSS issue, ansd more to do with my template, but I have to start somewhere.

www.rollthedicerun.com.au/index.php?option=com_content&view=article&id=19:2010-photo-gallery-&catid=2:gallery-

Displays OK in FireFox - but not in IE.

I did have Simple Gallery (not pro version) installed and everything seemed OK, but once I installed the pro version I got problems with thumbnail display.

Any ideas?

Could you please read the following post: forum.joomlaworks.net/simple-image-gallery-pro-%28plugin%29/image-gallery-pro-internet-explorer/

Hi
I recently bought sig_pro, and I had the same probleme than other guys : conflic problem with other css.
A applied a correction :
=> it worked for the 3 first templates, but not for the "sleek" template : images are not centered.

here is a dummy website (for testing) :
johann.servepics.com/joomla

I do not find where the problem is. someone can help me ?

Your link leads to an error...

there is no error in this link...  ???

I have just checked it out and sleek template works just fine...
And the pop ups are centered...

I don't want to speak about pop up, but thumbmails :

This appears under Ie8 or Firefox

This is a css conflict...
Just go to  templates/rosebonbon/css/style.css file at line 1084
and remove the margin you have given:

.article img, img.article {
border:0 solid #BDB7BC;
margin:1em;
}
