I have never understood why TM has such a "complex" method of uploading pictures. Most sites have a "Browse" facility that connects to your library, click on the photo you want, select open, and as the saying goes "Bob's you uncle" !
This method means that the site ends up directly hosting the picture itself, rather than linking to it, as is he case with Photobucket et al.
It might be easier for the user but especially in this day and age of massive MP counts for photographs, it means that the storage requirements for the site (and therefore the maintenance and running costs) increase by a couple of orders of magnitude.
In order to keep the costs down and simplify administration for Simon, I think that to use a Photobucket account for our pictures is hardly a great sacrifice?
