Ed,
I think what you're asking is can you insert a picture within the text like this...
Then keep writing your message below the image. Where it's not an "attachment" at the bottom of the message.
Then add another image like this...
Then, of course, continue your story again.
You need to have the images posted on the web somewhere. Mine are posted on my trading wantlist website using Yola.com to create my website. When I need to add an image into the post, I got to the image on my website and right click then click Properties to get the following window to pop up...
Highlight and copy the Address: URL in it's entirety.
Next you want to click the Insert Image Icon at the top of the Message window.
The following window will appear and you just paste the URL into the bar at the bottom of the window.
Click OK and Boom, the image is inserted. Just start typing again after the [/IMG] end tag of the image.
