Re: [flexcoders] Simple Code to load a jpg from a website, then load again and replace needed

[Daniel Freiman]

What error are you getting.  My guess is that the addChild() is blowing up
because you're trying to add 'content' to the application when 'content' is
already a child of the loader.  A displayobject can only be a child of one
displayobjectcontainer.  Loaders are fairly low memory usage.  I would just
add loader itself to the application and not worry about it.  If you're
loading hundreds of images and you start to notice a problem, only then
would I would about optimizing memory management.

What are you trying to make.  Based on what I see here, It's possible that
using a flex project as opposed to an Actionscript project will cut
development time significantly.
