btw Johns to "remove the box" you can't add them as an attachment to the post, you need to use an external hosting site (www.imageshack.us is a nice one) then use [ IMG ] [ /IMG ] (without the spaces) tags to put the picture in the post without the box.
Example(just hit the quote reply button to see what I did)
Btw your "what is this" picture looks like the tail of a Kole Tang.
Seems to work ok for me, you don't just put the link of the address in, you have to use the [im g] and [/im g] tags (no spaces in the tags), see picture below.
trying again. the first time i copied and pasted before hosting and got a big picture that took long time, 2nd time I hosted, then copied and pasted, took short time and got small picture. trying this third time to see what happens. The picture is of a local cold water anemone at the Alaska Sea Life Center in Seward.

The issue with the last two pictures you posted has to do with which link you copied on the page, what you did is copy the thumbnail link, if you recall there are a variety of ones. Thumbnails are fine and dandy, but if you want the whole picture you need to use the "direct link to image" URL that they give you, (atleast at image shack).
