If you don't want to use FB, just use the tapatalk app. While posting a reply/starting a thread just click on "open advanced options" tab that is located just above the keyboard and under the text window. Click on "camera" if you want to take the picture you are going to add or click "photo album" if it is already on your phone. Find your photo and it will ask where to upload it to. Select "Tapatalk Hosted" and it will add the link to your text window for you. The only problem is that the photo is hosted remotely and if something happened to tapatalk, you/we would lose the link. Same could happen with photobucket as well though.
Also, go into the "settings" tab on the main window and find "signature". Click that off, since it is annoying to see the additional message after your post.
I have a photobucket now, my name is justinsixx__ there if you wanna check out my truck and the progress it's made, also uploaded some pics of my Firehawk.
I have always used photobucket to upload pics to the forum, I even opted for the pro (paid) membership to ensure no bandwidth limits and no ads - I have been happy so far.
