Re: Copying input from the Wolfram blog

I'd view this as a suggestion to the folks at WRI to include a
notebook version of each blog posting for download from an associated
link.   It's a good suggestion!

Indeed each item in each blog posting can certainly be included in a
Notebook version.  I suspect though (but I don't know) that the blog
postings on http://blog.wolfram.com are not generated directly from a
notebook version by a simple applicatoin of Export,  but rather from a
more sophisticated  bit of Mathematica code that uses a notebook's
content and translates it all into something that Moveable Type then
can display. (If you look at the web page's html source you see that
it is Movable Type that is being used.)

In http://www.scientificarts.com/worklife/ (see
http://www.scientificarts.com/worklife/documentation/blogging.html )
there is the option of including a notebook version for each blog
posting.  (See http://www.scientificarts.com/worklife/wlfwblog/index.html
for examples; this is a case in particular, directly generated from A
WorkLife FrameWork where the notebook download link is adjscent to the
Permalink at the bottom:

http://www.scientificarts.com/worklife/wlfwblog/BE3390503366/BE3390503366.html
)

However, to quickly deal with your need to access the code displayed
as a gif on http://blog.wolfram.com, you should look at the source for
the page that you want and look for the Alt tag for the item that you
want the code from (look in a text editor).  You will find the code
that you want to ocpy there in the page source and can then make use
of it directly by pasting it into Mathematica.

I hope that this helps....
