Hi
I'd like to send a custom image not as a file, but as an handwriting image, so that the receiver sees directly the image, and NOT the link to the file!

This because I'm creating a script that
1) reads any mathematic formulas before sending the message
2) executes a dll that parses the text in a "Latex" file
3) converts the Latex file in a png image, that contains the mathematic representation of the formula!

But I don't know how to send the final image in chat window...

Thank you for any help!!

A lot has been written about using Ink for sending pictures in the past years (since Ink was available). So you might wanna search the forums with " Ink" regarding this. Bottom line is that this is far from easy to do. Scripts in Messenger Plus! Live also don't have any access to the needed stuff for doing this, as such you'll need external DLLs and you need to make an engine which sends Ink on protocol level.

As for using LaTeX, this also has been a topic since years and years. Many tools, plugins, etc have been released for doing this. For pulling this off with scripts you have almost the same problems as explained in first paragraph (since it also involves sending images).

You are far better of making a Messenger Activity, which are small applications running from within Messenger. In fact, this has already been done:
