yes its only when i send them to myself the text is there but it states attachment removed?
I will look into the higher resolution idea!
but why would the same picture go to everyone else except those with tracfone/verizon its the same resolution?
I believe Yahoo is owned and run by Verizon. Maybe that is the problem?
You could try connecting with a VPN, e.g. Psiphon https://psiphon.ca/ and that should prove if it is Yahoo and/or Verizon deleting the attachments. Because a VPN provides an encrypted tunnel through any filtering/censoring an ISP or carrier does.
