Welcome, fatroy
Yeah, she's lovely
Try this - right click a small thumb and choose "properties" from the options by left clicking that option. Among other info, the url string for that pic will appear in the general properties window. As a for instance, you'll see:
hxxp://members.simonscans.com/samples/samples1177606560/sith_Isabellea09003.jpg
(I changed the standard http opening to hxxp for this example because hotlinking is not allowed on freeones but as you'll see the actual url will begin with http)
Copy and paste the url into your browser address window. Place your cursor just back of the letters "th" in the the string "sith" that precedes _Isabellea. Backspace out the letter "t" and "h", then hit your enter button.
