The last time I bothered to look, this was phone, model, account, and
provider dependent.
On top of that, many of the phones have very limited graphics resolution, so
a small file is the norm.
Many of the phones have some sort of html capability, as well as an email
capability..
In other words talk to whoever sold you the phone, and look on the mfrs web
site.
Then look at the providers web site.
