Hello, the chrome.tabs.update has a callback parameter, does that help?

http://code.google.com/chrome/extensions/tabs.html#method-create

chrome.tabs.create({'url': 'http://chromium.org'}, function(tab) {

  console.log('Tab Created ' + tab.id);

});

Try adding a listener for chrome.tabs.onUpdated:

Hmmm...
chrome.tabs.onUpdated is an event and i can't check it once cause it
fires constantly.

>>>>>>>>>>>>
chrome.browserAction.onClicked.addListener(function(tab) {

// find parent dir
var findpardir = tab.url.lastIndexOf("/");
var pardirurl = tab.url.substr(0,findpardir+1);
// find location ext
var lochref = tab.url.split(".");
var lochrefend = lochref[lochref.length-1].toLowerCase();

if ((lochrefend == 'jpg') || (lochrefend == 'jpeg')) {

chrome.tabs.getSelected(null,function(tab) {
chrome.tabs.update(tab.id,{url:pardirurl});
});

// starts in 1 sec. (then the page loaded probably)
// but i will wait/check if it's complete

setTimeout('chrome.tabs.executeScript(null,{file:"script.js"});',
1000);
}

else {
chrome.tabs.executeScript(null,{file:"script.js"});
}
});

Here's some pseudocode that illustrates what I was thinking:

var tab_callbacks = {};

chrome.tabs.onUpdated.addListener(function(tabid, info, tab) {

  if (info.status != "complete") {

    return;

  }

  if (tab_callbacks[tabid]) {

    tab_callbacks[tabid]();

    delete tab_callbacks[tabid];

  }

});

if (/* we want to update the selected tab now*/) {

  chrome.tabs.getSelected(null, function(tab) {

    tab_callbacks[tab.id] = function() {

      console.log("tab finishing loading now");

      // do other stuff here...

    };

    chrome.tabs.update(tab.id,{url:pardirurl});

  });

});
