I made a port of the "Show the image"-Firefox extension (https://addons.mozilla.org/de/firefox/addon/1590) which can be found here:
http://code.google.com/p/show-the-image/

It opens the largest image on the current page in the current tab on click and the largest image in the current and all tabs to the right of the current on doubleclick.
It`s all about making the first steps in the extension system, but maybe someone is interested in this.

Cool! It works pretty well!

This great stuff, thanks

Due to the changes in extension system and packaging extensions i made
a new version.
http://code.google.com/p/show-the-image/

I installed the extension, but can't figure out how to use it. What do I click on? Do I need to add something to a toolbar, like you do in firefox?

If I go to extensions I can disable, or uninstall, but there is no help.

Help?

Well, i didn`t update the extension for quite a while and some major things have changed since i last worked on it.

I updated it now to version 0.1.8, maybe you give it another try.
And please add an issue on the projectpage if something does not work. Thanks.

Really good work, And This This plugin is pure awesome, simple, elegant, and efficient. Can already see how much time I'll save from using it and not having to switch folders each time I save a .png or 7z; really makes browsing go faster.

I've been using the firefox version for years now, and i'm very fond of it. i wanted to try your version as i use chrome quite as often as firefox now, but it doesnt seem to work for me. firefox plugin immediately shows the largest picture in the page on left click, and largest pictures in the subsequent pages on right click. this is very practical and handy. however with your plugin left click opens a dialog where you choose from the images in the page or page history. This would also be a practical feature for me if the images were clickable with middle mouse button (in order to load them in new tabs). Also, the double click does not work for me. I'm very much in need of a plugin that would simply show the largest image in multiple pages. I hope you consider my thought depeloving later versions of your plugin.
that aside, if you have time to spare, check out the "pterodactl" extention for firefox, it saves the largest images in multiple tabs to a specified folder. i used to use barracuda but it was too problematic. pterodactl work flawlessly accept certain webhosts like imagebam. it would be appreciated if you or some one else made a chrome version of it too.
thanks.
