Mass Sprite Sheet Expansion Battle & NPC

I have to ask... why do you always use two complete images tags for each one of the picture you post?

[img]http://myimage.png[/img] is sufficient. Are you like writing manually a tag for the image then select the image + open/close tag and click on the imagelink button?

It's not a problem in any way what you do in your posts, you can have 4 tags surrounding an image but I'm just curious to know where the mistake comes from....
