I think it works. For example, I change the content of “/wp-content/themes/twentyeleven/gallery-template.php” and every page generated by Gallery plugin are affected.
I got the same problem. After I replace the value of “text-align”, it works fine now.
Path: /wp-content/plugins/galeery-plugin/css/stylesheet.css
.gallery .gllr_image_block {
float: left;
text-align:center;
}
I have to thank you for creating this useful tool. But I found a little problem that confused me for a while. When I enter URL for each image and click “update”, a warning message popup and says “Requested URL not found”. After that, the URL is still save successfully. The plugin works fine now except this issue.
