The context, along with content, of an image is all important in the deciphering of its meaning (or lack thereof). The difference between the same picture of a seascape can change in meaning depending on what the image maker's intention was. If the shot was taken while on vacation it may just be seen as a document of the trip and lead back to thoughts of escape with family. If the shot was taken by an artist with ideas of representing the vastness of the ocean in opposition to the supposed vastness of human accomplishment then that meaning would be what may be shown. Where the artistic is intended to have a particular meaning, the non-artistic may not have this in mind yet still accomplish it. This is not to say that the artistic is more or less valuable than the amateur but that its meaning and context is more carefully decided upon and may be easier to find. If no meaning was supposed by the creator there still may be meaning in the eyes of the viewer but it is incidental meaning arrived at by imagined or real contexts from the viewer, not the creator. So, whether an image has inherent meaning or not, it will get meaning anyway due to context. The more we know of the real contexts, the more accurately we can interpret an image.
