A backslash is missing In file "plugins/content/jw_sigpro/jw_sigpro/includes/js/jquery_fancybox/popup.php", line 42, in the closing </b> tag. At least Firefox does not recognize the closing tag, making the (bold) caption stick to the "Image x of y".
this.title = \'<b class="fancyboxCounter">Image \' + (this.index + 1) + \' of \' + this.group.length + \'</b>\' + (this.title ? this.title : \'\');
should read
this.title = \'<b class="fancyboxCounter">Image \' + (this.index + 1) + \' of \' + this.group.length + \'<\/b>\' + (this.title ? this.title : \'\');
I am usually creating non-English websites. So I actually need the phrase "Image x of y" translated to the site language. Hacking the core file is no preferred solution. So please consider using a language ini file to customize that.
Edit: This translating problem also applies to buttons saying "Next", "Start slideshow" etc., although it is probably more difficult to customize this, since these texts are hard-coded in the javascript files.
