You can get a free account with a site like Photobucket.com and link your pictures from there. That's what I did for all of my picture posts.
I'm chiming in a bit late here, but I'd like to give my two cents on instructional resources for the self defense blade. Knife combat (most combat really, but knife combat in particular) is very inaccurately portrayed in films and other media. Real knife attacks aren't broad, sweeping, telegraphic attacks - they are quick, explosive, and don't stop.
Most knife fighting instructors will teach you about effective grips for a knife, the method by which you can achieve a cut or stab, and how to protect your own vital areas (carotid, brachial, subclavian and femoral arteries, stomach, etc.) from an assailant who also has a knife. Drills will usually include flow/form practice (how to move the knife smoothly from one attack into another), impact conditioning (attacking soft targets to get you used to real force feedback - my instructor uses stacks of car tyres), footwork and lots of repetition with a training partner to train your muscle memory.
The knife-fighting styles I have studied (KunTao and Lameco Escrima) emphasize aggressiveness and controlling the "power lines" in a fight (i.e. stepping to your opponent's outside and getting out of the range of their weapon, while leaving them in range of your own).
There are lots of resources available to you apart from Emerson's videos. Paul DeThouras is a famous practitioner of Pencack Silat, an art which makes use of the karambit. Rick Hernandez's T.A.C.S.A.F.E. series is good for KunTao knife combat and unarmed self-defense. One of my instructors here in California, Ron Balicki, has a video dedicated to the Lameco Escrima system popularized by the late Edgar Sulite which focuses on Filipino knife fighting - the series is available through ColdSteel.com.
See if you can find a proper instructor where you live, though. Nothing beats having an expert set of eyes to observe your form and correct your movements and posture so that you don't develop bad habits.
Best of luck to you! :thumbup:
