Hi Mate
If you go to this web site
www.villagephotos.com you can sign up for free ( takes about 60 secs and they don't want to know ya shoe size)
Upload your photos there . once you have done that, open the photo you will see a THUMPNAIL , under this you will see "Image URL and Tools" open this copy the "Public Image URL" then come back to the DSC open a new post , then use the "insert an image" button ( small with yellow background and picture of mountians and moon ) it is in the line of buttons that start with
B button,
once open PASTE the address ( URL) . click OK and hey presto your image should apear in the post ( to actually see it you will need to post or preview the post
hope it helps.
