Hi there - I have an iPhone 6+. The easiest way I find to upload photos on the forum is to select the photos I want on my phone and select the option to email them. I put in my own email address. It then asks you what size you want to send them - small, medium, large or actual size. I choose medium. When my phone receives them I then upload them onto my camera roll and use these photos to put on the forum. Because they are medium the forum allows me to attach 2/3 to each post. Hope this might work for you!
