Dexes/backdoors Tutorial (by iron)
Part I.DEXES
One way to find dexes is to go to a tgp site like al4a.com and check out the links.
I clicked on one http://www.babeprofile.com/tgpgals/oldies1020/oldies1020g.htm and just removed oldies1020g.htm and got a dex. Clicked on parent directory and had there i had a bigger dex.

Part II.DEXES
Here is an another way. still uses a tgp site goes to this link http://www.init4porn.com/lesbians21khun.htm . there i see that the pictures are in a folder for themelves click a picture http://www.init4porn.com/images/7125-lesbians.jpg removes 7125-lesbians.jpg and there i have a dex with lesbian pics http://www.init4porn.com/images/

Part III. Backdoors
Still uses a tgp site. Clicks on the link http://www.e-sexydreams.com/isabella/gallery6.html replaces gallery6.html with main.html and i have a backdoor. Many of the backdoor sites only changes the last html to things like this content.html, page.html, members.html, member.html and so on. Some of them uses the name the content/girl so if it had been the case in the URL above it would have looked like this http://www.e-sexydreams.com/isabella/isabella.html(This one doesn't work). You can do the same thing on the links ont the avs sites like sexkey.com, agecheck and so on.
