Feature request

BaseMedia represents Documents and Blobs, which are containers for data, id's, and metadata, and are useful for processing by embedding models and vector stores. Some vectorstores (e.g. Chroma) have methods like encode_image, add_images, which encode an image to base64, but there is no natural data type for this class of data. Document is a "class for storing a piece of text..."

We should add a sub-class of BaseMedia for Image to reflect the fact that you can embed and query over image data.

Motivation

See above.

Proposal (If applicable)

See above. Properties might be:
