sizing pictures

[SOJOURNER]

I've been told how to post a picture and have accomplished it several times.

I've been advised as to where to find picutes to post and am amazed at the stuff available.

Now I notice that when I attach an image it is in a box whereas other images posted by others are not - Why?

Also, when I have saved a pic, I have done just that, and I find that in this box format not all of it comes out or it does not move in the box - you must click on it to go to another screen to see it move. Why?

Posting in the alter ego thread had people talking about "blowing the margins". How do you know how big it is going to be or how do you set it to be a certain size and what size should that be?

Any and all help would be appreciated.
