There's several ways Dave, I don't know them all…and I may not be that accurate.
One, you can download an image to the free gallery here at TP...Go to your gallery and download from your home PC. ...then you'll have somewhere to host your images you'll be able to show to us in a post/thread. (More instructions available on how to link in the information in threads found at the top of most main forums.)
Second way is to host somewhere else and link from their, many people have galleries on line already.
Linking code goes something like this, (It’s also automated to a certain extent with the 'insert picture' tool found at the top of an editing/post page)...
IMG[]http://file location/folder/image.jpg[/IMG]...that will show your image where placed, as long as you have the address right. (correct the first img tag same as last one, img inside tags)
So its host somewhere first.
(Most people have 50+meg free with BBand packages btw, you’ll need an ftp transfer software for that though…often found free)
Then place a link to those stored images…with a similar link to above.. In a post so we can see.
Hope that’s about right.
