Some android and iphones may not have a default app that resizes pictures before posting them using our BBP Mobile Forum App. If your default picture app doesn't support this function then you may want to try downloading a secondary picture app such as Quickpic. Then when you attach an image to your phone post it will prompt you for which app to use to select a picture. Choose Quickpic or whatever other app you've chosen to select the image and it should resize it properly for posting here to the forum.
