Photo upload

[JHZR2]

Only works about half time from my iphone 6s running the latest ios.

Some work, others give an "upload failed" message.

Is there a size limit?

I have not tried uploading from my iPhone.

The issue could be the cell/wi-fi (wireless) connection.

I use Photobucket (FREE) and cut and paste the IMG line.
I've been using Photobucket for years. (ads are annoying)
The ads go away if you "subscribe". I just click "go away".
