Coping Icons?

I'm making a website for my map and I want to use the item icons on my site. How do I export the item icon images from the editor into a file where I can access them to put them on my website?

export as tga
convert tga to jpeg, gif, bmp, or whatever else is suitable in webpages

come to think of it, ou may be able to use tga files on a website. not sure about that.
