Here's a quick and easy way to have text wrap around graphics in Scrippy.  All you need to do is enter the graphics INSIDE the message area, rather than inserting them as a positioned image.  To do this, while in the message area, place your cursor next to the word where you want to insert the graphic and simply click on Insert and then click on Picture, or you can use the blue and green icon on the tool bar.  This opens up the Insert Picture Window where you can browse and select your graphic.  After you've found the graphic you want, while still in the Insert Picture window, you can tell Scrippy to have the text flow to the right of the graphic or to the left of the graphic.   If needed, you can also set the number of pixels you might want as a margin around the graphic, or just on certain sides.  In this example, I left the margins set a zero for both graphics.  When you're done making your selections, just click OK.  

If you want to change an option you selected, just click on the graphic to highlight it, and click back on Insert > Picture, or the little green and blue icon, and you can change the settings as needed.

NOTE:  If your graphic is moving down the page rather than the text wrapping around it, click on the graphic to highlight it and drag it up or down into the text and the text will begin wrapping around the graphic.  

NOTE:  You can add your graphics BEFORE you type your text, but they will usually move down the page.  In that case, after you've written some text, just drag the graphic up to where you want to insert it and the text will start wrapping around it according to your instructions.
