How do i can change my instant preview image?

[webit40]

Since we've put an index.htm file indicating that our webiste is under reconstruction and have removed it few hours after, the instant preview picture still showing the informative message. It has been 40 day since and we've submit our sitemap few times. Is there a way to change it manually?

One thing you could try is to put the following meta tag on the page, and once Google re-indexes the page, remove it immediately.  This tag will take down the instant preview, but also takes out your meta description on SERPs, so you'll want to remove it as soon as Google re-indexes the page. Once you remove it, Google will (hopefully) create a new snapshot of your page?  I have no idea if when Google re-indexes the page if they'll go create a new snapshot, or dig up the old one to display, but it seems like there should be a fair chance they'll take a new one?

Again, I've never tried this, so I'm only endorsing it as a possible idea, it is not a tried and tested solution.
