Super easy - great new feature. But it would be great if you can link the pictures to a page...is this possible? For example, if creating a gallery of products it would be nice if you could click on a particular image to get to that product page.

You are almost at the point in the journey where so much is available, if I might suggest something, you already have it (but I missed it). 
 
There are often questions around "how good is good enough?" and every where on the Internet and in business plans you see =be unique", "be valuable", or "don't be kool-aid". 
 
I would bet you have a way to use the blog platform to evaluate whether a new blogger could have measurements as to whether the info was unique, offered value and/or was helpful. Yes? Since the advent of buttons to click, Twitter, etc., commenting has evolved to something more.  
 
Just as you have to decide: Does this hit the mark? Was it what people need or want? What are your measures?  
 
Title, email, calls to action and content focused... all good. How do they know? Maybe there can be "American Blogger Idol" with three judges in public eliminating the worst. 
 
Keep it up. You are doing great. 

@Peter The image file names and captions are indexable. 
 
@Mike Thanks for the lovely words. Any thoughts on next items you'd like covered?

Thanks for the added tool ... and the simple show and tell. Gets right to the point with no hype or spin. Way to go.

This is great! I've been waiting for something like this. Are the individual photos SEO friendly? In other words is there a chance they'll come up in Google Images if the stars align? I know we have a lot of photos already show up in Google Images for longer tailed search terms. I hope this is an extension of that. 
 
Thanks!
