Uploading photos?

well my dear it is really easy in a file name you can put a name of image of your choice then description if you have any info about it so put it in ..and then tags so there put the words which is related to picture or your description///

The photo filename is the what the pic is called in your computer. The photo subject is what the picture is or about. Photo subject is where you go into detail about the phot. Yes people can see the subject and the discription of the photo. I think the purpose is for people to understand what the picture represants to you. Hope this answered you questions. Good luck here at mylot!
