I'm not sure how most users post pictures but i use photobucket. I was taking pictures on my phone, emailing them to myself, saving the picture from the email to a folder, opening up explorer window and then going to photobucket then downloading pictures from the folder to my
www.photobucket.com account.
Well, there is a photobucket app that allows you to send a picture right from your phone to your photobucket account which then can be used to post here. I am active in many forums and this forum, more than most forums, is probably in need of more pictures in the posts (try reading reeving posts with no pictures when you aren't familiar enough with it to imagine what they are writing about).
If anyone has any questions don't hesitate to ask.
