I find the easiest thing to do is just download tapatalk on your phone for free and post pictures in topics that way...no bs. Works just like facebook messenger for posting pics - you just upload them and you're done. Makes life a lot easier, plus you can attach pictures to private messages just as easily without any formatting.
Tapatalk is an app that allows you to access almost every forum so as long as you have data, you can find THP and then you're golden. If you don't have data and can only use your computer to upload, it won't help (if I'm understanding your question properly).
