Nice trick
...but the 2 pictures you showed are different lol...
For those who don't understand, here's a slightly modified explanation:
1. Leaping Bottlenose Dolphin
Free picture (small size):
Code:
http://p.webshots.com/ProThumbs/18/78218_wallpaper280.jpg
Premium picture (wide size):
Code:
http://p.webshots.com/sym-cache/ProInternalUse/18/78218_poster2000.jpg
2. Doggie picture (I don't know what's the real name)
Free picture (small size):
Code:
http://p.webshots.com/ProThumbs/45/39245_wallpaper280.jpg
Premium picture (wide size):
Code:
http://p.webshots.com/sym-cache/ProInternalUse/45/39245_poster2000.jpg
The trick is to:
Right-click on the small picture to find the image location of the 'Free' picture (small size). Then, modify the URL to find the 'hidden' link for Premium picture by doing these:
replace: ProThumbs with sym-cache/ProInternalUse
replace: wallpaper280 with poster2000
Now you know how to get Premium pictures for free from:
Webshots (Pro Shots)
