Sounds,
I notice many sound packs available. Which is considered the one to use?
How do you post jpegs here?
Everyone has their own favorites when it comes to the sound packs, I would just save a spare copy of the "sounds" folder somewhere so you can go back to defaults if you don't like it and try a few of them out.
Here's a quick answer about pictures I used in another thread
==============================================================================
First you need to find some web space to upload the picture to, there are a number of free services available (photobucket is one I know of but I know there are others). Once it's uploaded you just need to put the URL inside the image tags and you're off and running.
the image tags use the square brackets [ ], I'll use parenthesis so you can see the tag
(IMG)http://i448.photobucket.com/albums/qq209/Soulyss/P39snapshot.jpg(/IMG).
If you replace the () with [] brackets you'd see this.
===============================================================================
The exception to this rule is the forum listed further down the list called "Films and Screenshots" Which can have the pictures uploaded directly from your hard drive.
