i HAVE PS 7!! LOL!! i GAVE UP ON THE CS PS!!
lol... much better... actually my friend "PUNXTLYE"... he's better than me when it comes to manipulating pictures. but guess what, im using CS3 and he's using PS7 only... it doesnt make a difference actually... all you need to do is to DL some brushes, textures and patterns... also if you care to DL a gradient its also nice... but we can make our gradients though by adjusting only.
re-edit: download some brushes that's compatible with PS7... because you might download some brushes for specific photoshop version like CS2, CS3 and CS4...
so if you might wonder why the brushes doesnt work... it only means that its not compatible to the version of the photoshop of yours.
