kiki, it "ain't no big spagegi" to post pictures. You enclose the commands and url in brackets like these: < > and on other boards, these: [ ]. Always be sure to put the last one on, it's called closing the tag and it won't work if you don't--and unless the board is set up right an open tag can cause everything that follows to be bolded, italicized, underlined, or whatever. Here is a little lesson. I will get a pic from my image shack account and show you how it works (and you should open one of those. They are free and you can store all the images you want there and they give you the code; all you have to do is copy and paste).
Here is the picture and under it I will show you how it is done.

Notice there are blank spaces after the first tag and before the last one. You don't need spaces there but if I didn't put them it would "hotlink" and I couldn't show you what to do. So be sure and don't leave those spaces. The ONLY space you need is between the img and the src (means image source, or the url where the image is hosted). If you just found a picture you like on the internet from a site that allows direct linking you could post it from there by doing a properties search and getting the url. Just right click on the picture and it will bring up a box and that is one of the items of information in it, along with the size (in pixels). Hope this helps.
