Hi Bernice,
I guess your pictures are stored on your hard-drive at home and not on the internet (using for example
http://www.flickr.com ,
http://www.photobucket.com or similar services)... in that case the [ img][ /img] command won't be of any use and you will have to attach the photos to your post.
To do this, write your reply, click on Attachment - Browse..., select the first picture file on your hard-drive and click "Open" - this should enter the path to the picture file into the "box" next to "Attach:" - to attach a second picture, click on "(more attachments)" and repeat. You can add up to 20 pictures or up to 5000 KB (whichever is less). For many and/or large pictures, uploading them to one of the web-sharing services might be a good idea, though, to save server space on KF.
Should you need any further assistance, please do say so.
Best wishes,
Wolfgang.
