We just released two new features: an image crop & zoom tool, and an add-on that will make it easier for visitors to subscribe to your blog's RSS feed.

The crop & zoom feature lets you adjust your images on the fly within the editor.  For example, you can turn a rectangular full-length photo into a square head shot.  Here's how:

• To crop, mouse over an image and drag one of the lighter-colored squares on the side of its frame.  (You can still resize the image using the darker-colored squares on the corners of the frame.)
• To zoom, use the slider that appears when you mouse over an image.  If the image is small, you may only see two buttons for "zoom in" and "zoom out", and you can click those instead of the slider.  What's more, you can also reposition an image once you've zoomed in on it by dragging it within the frame.

Cropping and zooming usually requires special desktop software, but it's now standard for Webon images.

For bloggers, we've also added the Blog Subscribe add-on, which makes it easier for visitors to subscribe to your blog using their favorite RSS readers.  If they're signed in to one of the popular readers like Google or Technorati, subscribing only takes a couple of clicks.  Otherwise, they can copy and paste the feed URL.

If you run into problems with any of these features, please let us know using our help system.  Enjoy! 

Today we're unveiling a new feature that we've been working on for quite a while: user-created add-ons.  These add-ons use the OpenSocial API, an emerging standard for socially-enabled gadgets supported by folks like Google, MySpace, and Yahoo!

What does this mean for you?

If you're a site builder, you'll ultimately have a much larger library of add-ons to use with your site.  You'll be able to choose both from the add-ons we develop and from the add-ons shared with the Webon community by developers.  In addition, these user-created add-ons can take advantage of user profiles, friends lists, and other social features.

If you're a developer, you can now extend your site's functionality by creating custom add-ons.  What's more, you can easily share your creations, giving them a larger audience than they otherwise would have.  And because our add-ons use the OpenSocial API, you don't need to learn a proprietary language to create them.

This is all part of our goal of making Webon a user-extensible platform, not one that's defined solely by us.  If you'd like to try your hand at creating an add-on, check out this early peek at our Add-On Editor.  After you've saved an add-on, it'll be available the next time you edit a site; just select "my add-ons" from the pulldown menu in the Add-Ons window.

Please note: we don't yet support the entire OpenSocial API (version 0.8 to be precise), and we're still working on developer documentation.  But we wanted to let you start playing around with the editor so that you could give us feedback.

Enjoy!
