Using 'safari' as your browser, you can upload directly to here provided you resize it first to a smaller file or you can use tapatalk (you have to pay for this app) or get a flicker account that is free and load all pictures there then link it to here.
I use tapatalk. It was a dollar app and I think inlaid another dollar or two for unlimited image hosting. It's made my forum experience amazingly simple and a joy to use.
