Help Needed

Around 2002 i saved some pics with fotopic.net .... loads of pics play off final city v qpr 2003 many away games plus the folowing years .... I have my old emai laddress plus password i can get into the site and it tells me i can save them as zip files???
I have tried to save them but they end up as thumb nail size. Any wizards out there that can help?? Maybe a simple task ...... Any help to get my pics normal size appreciated
