Lee, no - what you are doing is fine using the upload feature to upload an attachment. Tommydelvis isn't doing that. The last one he attempted to post was given at address of
http://c:/Users/tommy/Pictures/2008-12-09%20camera/camera%20043.JPG which might be an interesting picture but it is on his C drive. He must be using Vista due to the location of his Pictures folder.
Big difference intrying to directly link a filein your Pictures folder ...and uploading an attachment.
