How to add pictures to my post?

I want to add some pictures to my post and I don't know how?? Please help me!

you mean in the post self then search for a pic copy(ctr+c) and put [ img ] without the spaces and than paste(ctr+v) the image then put [ /img ] without the spaces again so you got [ img ] url [ /img ]

if youre talking about a pic in your sig. find it on the internet (if you cant find it on the internet, just upload it into the offical attachment thread in off topic) the type in;
[-IMG-] the adress of the image you want to have [-/-IMG]

and remove the -'s. (i had to put them in there, or it would think i was trying to show an image, lok for the adress "the adress of the image you want to have", find nothing there, and have onyl a red X.

if you want to just add images to your post. click the attachments button when replying, and upload them from your computer

You can also upload pictures, however if they're too big they show up as thumbnails. On the bottom area of your reply, there's a button that says manage attachments. You can upload image files (and many other types of files) and they will show up.
