what is the differenc between photo & picture?

i think sometimes they are equal but not necessarily so

 while talking about photograph, which means a pic taken by a camera, these two words mean the same thing

 but picture is not limited to photo, it cud also refer to painting/drawing, etc.

hope it helps

hello  eshq

i have many posts regarding  the difference betweeen words  you can check them

any way to your question  picture is more general than photo 

and we have many differences regarding part of speech and meanings 

so if you are interested in word differences  i recommend you read about semantics

i will be glad to help you but right now iam busy with my exam when i will be free  at your service

c u  soon

Photo: A photograph (often just called a photo) is an image (or a representation of that on e.g. paper) created by collecting and focusing reflected electromagnetic radiation. The most common photographs are those created of reflected visible wavelengths, producing permanent records of what the human eye can see.
IMage:In common usage, an image (from Latin imago) or picture is an artifact that reproduces the likeness of some subject—usually a physical object or a person.
Images may be two dimensional, such as a photograph, or three dimensional such as in a statue. They are typically produced by optical devices—such as a cameras, mirrors, lenses, telescopes, microscopes, etc. and natural objects and phenomena, such as the human eye or water surfaces.
