Images are shown as list, no thumbnail list

ok fixed that by deleting listing classes from theme(it was some kind of interfere with plugin css classes) – not best option… but it worked and i’m using listing from other plugin, so it should be no problem.

Just would like to know another thing – what class should i use for setting left/right margins?

already tried:

.image-gallery
.image-gallery li

but it doesn’t affect thumbnails in any way.

ok, used:
.image-gallery a

and it worked, seems like i resolved problem by myself ;p

Still would like to use so other way, than deleting few line of CSS code from theme(css override) but well.

Sorry, what’s wrong with the CSS you have used? Did you mean you had to delete CSS from the plugin? If you can show me a live URL I can help you.

Regarding the thumbnail sizes in your first post, did you regenerate the image sizes using a plugin? images in WP do not update automatically when you change the size.

Nope, i deleted CSS from theme, code i had to remove:

#blog .section  ul { display:block; overflow:hidden; padding: 0 9px 20px;}
#blog .section  ul li { display:block; overflow:hidden; background:url(images/orange/bullet-1.png) no-repeat left center; line-height:30px; padding:0 0 0 17px; font-size:13px; color:#787671; font-family: 'DroidSansRegular';}

About thumbnail sizes – haven’t tried to regenerate those, but it was actually the least of my concerns ??

That’s fine, you’re free to edit/remove code from your theme if it’s overriding the gallery, happens all the time. Let me know how you go with regenerating thumbnails.
