Does anyone know if there are any decent apps for uploading photos on the web? I know there's an iPhone flickr app and several photo editing apps that let you upload to Twitter, flickr, me.com, Facebook, etc, but I'm wondering if anyone figured out a way to allow more generic file uploading? Like here on Mac forums... If I click manage attachments the "choose file" option is greyed out. I also visit some photo galleries around the web and it's the same there... Anyone know?
