Thanks catcus, i would not of known you could do this direct displaying of an image in a forum post without you mentioning it.
I wanted to provide some more detail for others users based on your suggestion.
a open square bracket is [
a close square bracket is ]
for images, use the tags marks, img and /img
img is the tag mark that is used at the beginning of the and /img is tag mark that is used at the ending
when using tags marks, place them inside of square brackets
(open square bracket)tag mark used(close square bracket)
so your tag would look something exactly somthing like this,
(open square bracket)img(close square bracket)http://www.flickr.com/directory/grahicfilename(open square bracket)/img(close square bracket)

in the pic above i used the image tags marks (img and /img) inside square brackets with the below url in between the image tag marks

my litte tutorial
I am using Firefox(ver 3.5.19) web browser for this tutorial.
1. find a picture on flickr(you do not have to be logged into any account)
2. notice that in the above, catcus did not have to log into my account to present a thumbnail of my picture of an apple computer
apple computer? the pic of the apple computer was uploaded from my iphone, that i had taken weeks before, to show somebody that i had gotten their computer working.
3 currently at flickr, while viewing the image(in probably it's normal viewing state), there is an icon at the top(a +(plus) sign inside of a magnifying glass). Press that icon.
4. In the upper right of the next web page presented to you, click "view all sizes"
5. Then on the next web page presented to you, you will have choices of different pic sizes. Now pick one size to view the image with.
6. Now you use the copy and paste features of your operating system.
6a.The image should be displayed in your web browser for the size image you chose. Right click on(inside) the image shown on the web page being viewed, and then a dialog box should be presented to you in a pop up fashion allowing you to make a choice of variable selections on what to do next(basically what to do with this image). Choose the selection "copy new location".
6b. Then you insert(paste) the web page url descripton to the graphic image from flickr into the contribs.org forum post between two square bracketed image tags.
example
(open square bracket )img(close square bracket)http://farm6.static.flickr.com/5075/5859144433_6c9cc2ce97_m.jpg(open square braket)/img(close square bracket)
