If tineye does not return any hits for a provider image I submit, does that mean the image is probably real and unedited?

thank you!  is there a better way please?

Tineye does not contain every image known to man.

thank you!

1) Use tineye
2) Use Google Image
3) Check for reviews

How about "maybe?"

Or how about, in the spirit of the late Harry Caray, instead of "is probably" :  " … might be, could be  … ?"

Or even "might could be," if we were somewhere in Appalachia.

Try proving a negative. It's more or less the same.
