I've tried 3 separate posts, besides the one that while listed, doesn't work.
It seems every time I attach a picture from my Galaxy S5 the post fails. Must be a size limit?
Same with my wife's phone she has s4 and pics must be sized to large. She can only send one pic at a time in text messages too. Where I can send multiple with my I phone.
the S5 has like a 16 megapixal camera on it. lol.
You'll need to upload it to a site like photobucket or Imgur then link it to the forums.
In regards to text msgs, because of the high res, the images will be larger in file size. All carriers have limits in what you can send via sms and they are not keeping up with technology.
