Anne - try this....
Open your webspace page or wherever you have uploaded your pic to.
By your pic you will (hopefully) see a URL title for the pic which usually starts of :
http://img.(followed by a description of your pic).jpg.
Left click on that line of text to highlight it - then click 'edit' then 'copy'.
Then go to the forum and select 'reply to topic' of the appropriate section where you want to put it.
Click on the yellow envelope thingy which will put img and /img in the text space.
Left click in between the img and the /img then click 'edit' and 'paste'
You can then click 'preview' to see how it would appear.
If you only see a square with a red cross in it - you haven't watched my lips closely enough... put your computer back in the box and take up flower arranging

Seriously - if that doesn't work email me your direct address and I will write it all out for you from the beginning... XX
