Thanks Nicolai, you were right. The problem was not on the image format,
but on the parsing of the date. It was just that my non working test
were located at places where, coincidentally, the images were on jpg
format and I was misreading the signals :-). Now both, date
scrapping/formating and images in jpeg and png, are working properly.
Last version of Dataviz[1] reflect that changes.

Hi all,
On [1] you can see a small video showing the support for word clouds and
data scrapping from Twitter for some public profiles (including mine). As
you can see the visualization is embedded on grafoscopio trees/documents
that provide context for the scripts and combine them with other
documentation. You can create your own visualization by running the code at
[2] and changing the profile name.

So here are my usual questions:
a) The code that puts an image in a name cloud accepts only png images and
when the avatar has jpeg images I got an error. There is any way to make
the
RTNameCloud to work with jpg or to convert it to png. I was looking at
Sven's documentation[3], but I can't make it work in my context (jpeg is
taken from the web and converted to png without using the file system).
Why do you need a png ? The R TNameCloud does not use a image on its own, its
your code that adds a RTBitmap, and as far as I can see, the RTBitmap
only works with "Form".

b) There is any way to go beyond 19 tweets. In recent conversations with
Paul[4] he taught me how to extract tweets properly from a page using
ZnClient, but it gets the last 19. There is any way to make ZnClient to go
beyond that initial request and get, lets say 100 or more tweets?
