Ok, some people still saying that they can't upload pics.
I use the Tapatalk app, it's much easier than Photobucket IMO.
Sadly, as I use an iPhone, I'm not sure how different it is to do it using android software.
1) Press the Tapatalk icon on your home screen.
2) The app will open and show you a list of sites that you will need to have stored - obviously RAD being the one you need.
3) After selecting RAD, it will open up to the RAD home page, listing all the various sections, as with the forum.
4) For the purpose of this tutorial, I'll select 'The Lounge', so will scroll down to BMX Free Area/Zone, then it will open up a sub catagory.
5) Then, select the thread you wish to post your pics in.
6) Press 'post reply' and a new page will open up.
7) To add your pic(s), press the circle with a cross in it on the left hand side above the keyboard. Then you'll get the options to add a pic, or use the camera etc. Use the 2nd icon along, to access your photo library.
When you've selected your pic, the image code will appear on the post editing page.
9) Repeat step 7, should you wish to add more images.
10) When you've added all your image codes, and any text, press create, at the top right of the screen.
11) When you've pressed create, you'll see a buffering icon will appear for a few seconds. Your post should upload immediately, but occasionally you may get a message saying it hasn't. In my experience, this is bollux, and you'll find that it has uploaded successfully.
Hope this helps.
