The issue that I am noticing is not coming from the curvinosa theme. I still see it when I invoke your site with another theme ( http://fotometeo.ame-web.org/index.php?theme=rainy_day ). So it is coming from a plugin or modification made to a core file. If you care about search engine rankings of your site, I believe they will discount the site because of the improper html ... otherwise, it's no big deal, I guess.
Thank very much Ron
I appreciate very much your interest and your help.
In fact I think I really need it, because I know very few about php, and I don’t have anyone to help me. I would like to solve the problem you mention, but now I’m more worried than before, because I think the problem you are talking about is not the same the one I was aware of.
In fact, I don’t know which problem you exactly are detecting in my gallery
I’m also worried about breaking any rule of the forum, as this thread is about 'Enlarge it', so, in case you want to help me, I don’t know where it would be possible to continue talking about my gallery’s problem.
By the moment, I have uninstalled one plugin: LightBox NotesFor.net, because it was not much useful with 'Enlarge it', and also because now I have your slideshow plugin. I hope that the problem you say was caused by this plugin and so now it may has disappeared...
