I installed tapatalk but after opening the photo contest forum page I am unable to find the contest thread and upload the photo
on your phone:
you need to be in the thread , and reply to it, and then use the attachment , it will bring you to your photos
on your computer:
in the thread use the quick reply, and use the Icons bar , look for, and use " insert image"
this will give you a insert image converter page, now select "from computer" hit "select file" this will bring you to your photos, select the photo and it will convert it to this forum, then when it's converted it , select upload files, and your done, this will put a code on your quick reply page.
finish your comments hit replay.
