Hello Robin and welcome to the forum.
Try these easy steps;
Start a free account at one of the hosting sites below;
http://photobucket.com/
http://www.villagephotos.com/
http://www.putfile.com
Once you set up a free account & follow the upload instructions on their site your pictures will have a URL address such as
http://www.filehigh.com/serve/13386/247097.jpg
Then all you do is copy that url (typically with a cut and paste) and put it in your post. Others can then click on it and will be able to see the photos.
What would be even better and is very simple, is to make the photos be right there in your post like you see in other members posts. To do that the last step is to put the url address (represented here with **) in between the following;
[IMG] ****************** [/IMG]
Then your photo/s will automatically be there when people go into your post.
If you run into any trouble or have any questions just PM me and we will get you squared away.
