Mobile minibrowser: how to reload image while maintaing page offset position?

Answer 1

Isn't it lovely when you answer your own questions? Hmmm...

Anyway, according to this, some properties/functions for the JavaScript (JScript?) window object have different representations according to the choice of browser (Firefox, IE, etc.). Therefore, a possible page vertical offset function would be

function setPageVPos(w,vpos) {
  try { w.scrollTo(0,vpos); } catch(e) {}
  try { w.document.body.scrollTop(vpos); } catch(e) {}
}

The first tries with the window.scrollTo implementation in Firefox browsers, and the second tries with the document.body.scrollTop implementation in IE browsers. I've tested in both Firefox (desktop) browser and in a HP iPaq IE-like (mobile) minibrowser and works on both.
