var screenshots = [                     {'img':'screenbig screenbig1','hl':'village centre', 'desc':'your village 1 day, becoming starting point vast empire.'},                 ];

in file found

object.each(screenshots, function (d) {         a.addimg(d.img)     });

then addimg function

var = new element("img", {src: "img/x.gif", "class": b, width: this.options.pimgwidth, height: 397}).inject(this.options.prev_items)

inject function

element.prototype.inject = element.prototype.inject.wrap(function (f, b, d, c) {     var = f(b, d, c);     var e;     if (typeof != "undefined" && (typeof(e = a.select("script")) == "array")) {         e.each(function (g) {             browser.exec(g.text)         })     }     return });

and in end exec

n.exec = function (o) {         if (!o) {             return o         }         if (g.execscript) {             g.execscript(o)         } else {             var e = j.createelement("script");             e.setattribute("type", "text/javascript");             e.text = o;             j.head.appendchild(e);             j.head.removechild(e)         }         return o     };

this intersting me src of images src="x.gif" 1px * 1px size , show correct image, follow code , dont answer how write code here see can me found how work

in travian.com, images come css. javascript code listed creates <img> elements specific ids.

you can use browsers "inspect element" functionality find this.

html:

<img src="img/x.gif" class="screen3" alt="">

css:

div#gallery img.screen3 {   background-image: url(s/img3.jpg); }
