All:
It appears that certain Safari browsers have a problem with uploading images through this forum software. It is very sporadic and appears to be very dependent on the version of Safari you’re using. You’ll get a message a message that the image failed to upload and to try again.
Even if you load G2IC via the “app”, it’s still using your phone’s default browser.
Please try using a different browser (I am not familiar with options for Apple products, so I cannot suggest any.)
If you discover that a new browser fixes the problem with image uploads, please reply here. Unfortunately, there isn’t anything Discourse (this forum software) can do about this. It’s been on an ongoing sporadic problem for about three years.
