I am building an adult site with a gallery that will have categories. My question is, take for example, if I made a web page called "masturbate"... on the page that will have the gallery, would I have to include articles that include the keywords that it relates to on that page in order for it to get indexed better? Or would having the keywords in the "image name" be enough? I mean, I know I could add keywords in the "meta keywords" but if there is no content on that page and only images, wouldn't it be bad? I see many sites actually with very little content(text) on their gallery pages so how do robots crawl those sites effectively?
