Using a standard HTML form with a file input it is possible to upload a file directly into the DAM. Use a form something like this:
<!DOCTYPE html>
<html>
<body>
<form method="post" action="http://localhost:4502/content/dam/geometrtixx.createasset.html" enctype="multipart/form-data">
<input type="hidden" size="20" name="_charset_" value="utf-8">
<input id="file" name="file" type="file">
<input type="submit" value="upload">
</form>
</body>
</html>
Change the path in the form action from /content/dam/geometrixx to whatever DAM location you wish.
If you select a file named my.gif, it will create an asset in the DAM at /content/dam/geometrixx/my.gif
It will go through the normal workflows to give you the various asset renditions also.
