Ok, lemme try this...
PART ONE
-go to the Pe2K Home Page
-click 'SPRiTE RESOURCE' at the top left corner
-make a choice from the different categories, then pick the poke/ item/ sprite of your choice
-RiGHT click it(the image), scroll down to the bottom of the lil window and select 'PROPERTiES'
-take note of the URL(http) address. The entire thing will be needed to insert sprites. eg:
http://www.pokemonelite2000.com/pkrssh186.gif
PART TWO
-go to the user contol panel(
User CP) at the top left corner of
this page, the one you're looking at right now as you read this post.
-edit signature
-type the URL of the sprite you want. You could also just copy and paste it from the properties window.
-at the top of the compose box, to the right of the
bold,
italic,
underline, alignment, indent, etc, there's a lil box icon

highlight the URL of the sprite and click this icon. The
insert image icon, ooh, ahh...
-that should put [IMG] & [/IMG] on either side of the URL.
You're done. Rinse and repeat as needed.
