Perhaps. But now you probably know that the FB uses search technology that is based on texts.
I wrote ten years ago:
"...an image or symbol may be related by or to a graphically similar image or symbol that is explained by text.
...an image in a page of a social network may be preceded and/or followed by textual information, e.g., from personal blog, that can provide a basis for associating the image with textual subtext.
Or, an advertising agency may desire to find an image that conveys specific feelings to the exact desired audience. The agency can search for such an image in a segment of a social network if the agency knows that this is the right audience for the purpose. Images, photos, symbols, drawings, etc. in social networks often are accompanied by or associated with textual comments. If there is no text associated with a particular image, a feeling or sentiment that can be associated with that image may be deduced from textual information that precedes and/or follows the image of interest in time, e.g., in personal blogs of members of the social media of interest, where (i) explicit descriptions are comments in textual format concerning the particular image of interest and thus, if present, can help form the context of the image, and (ii) implicit descriptions are textual information that precedes and/or follows in time the image of interest and thus can help form subtext associated with the image of interest.
...it can be impractical and/or unproductive to rely solely on explicit text of an advertisement, comments to an image or a symbol, etc., a website name or address, and/or even on the words of a search query, because they may not accurately or sufficiently fully convey implicit thoughts or emotions that are not readily apparent from the words of the text. For example, the social network enterprise may not have a sufficient advertising budget to afford skilled professionals to write advertisement texts or to do extensive market research for the right expression for an audience that the enterprise would like to impress and engage. Or, a network may not have the skill or means to discover images or symbols that convey the desired meaning or sentiment of emotion to a specific audience."
