I believe after speaking to someone, I just choose a file and upload it. Select the next one and upload it until eventaully all files have been uploaded. I have a web page with a number of different elements - HTML, jpeg's etc. I wasnt sure if I could upload only a single file then the next upload would overwrite the previous one, but as far as I understand now each upload will add the relevant item along with the previously uploaded elements. Please corret me if this is wrong.
