Hi there. Take the pictures, resize them to about 480x375, put pictures on a web-site(the 'host'), start your post here, click on IMG, insert in the box that comes up the URL for the picture.
The URL can be obtained by right clicking the picture when it is on a web-page and copy the image properties then paste into the box(see above).
It should look something like this....
http://www.btinternet.com/~paul.evans28/Airbus.jpg
That is the URL for the picture I posted above. I hosted it on my free web-space that I get from BT internet, my ISP. Every ISP should give you free web-space, if unsure go to your IPS's home page and look at the FAQ there.
It looks complicated here but it really is easy. If you still can't do it, send the pictures to me, I will host them and put them up for you.

Good luck.
