Ok so i am just getting into actual good photography and i was wondering i do i change the image size so i can post it on this site? I am using iphoto if that means anything to who ever can help me.
Er...it took me a few attempts to try and understand what you're trying to ask and I'm still not 100% sure what it is. You want to post images on this site? Simplest way - Upload to imageshack.us and link it to here. Or if you want a more permanent way, get a flickr account.
or you can just use the built in forum attachment feature
