Thank you for the response. That might have something to do with it. I hadn't done that, mostly because I'm still using the same phone device I've used for at least a few years and haven't changed any settings that I know of.
Looking at recent pics that I'm trying to upload they're over 6mb.. (6.88mb for the one I've been trying)...
I have older pics in my RCU "album" which are down in the 3mb and smaller size, some even down in the kg range. So it stands to reason my files exceed limits. I can upload and post smaller pics from my album, which is RCU based. I've just never had any restrictions, but yeah maybe the files are too big.
You definitely just gave me something to look into.
Thank you again, much appreciated.
