recommendation on bytea or blob for binary data like images

Hi, I'd like to know what the official recommendation is on which binary
datatype to use for what situations.

I'm working with the Open For Business (www.ofbiz.org) framework, which by
default maps binary data, such as shipping label images, into OID field
types. In general, the data is far less than a gigabyte in size. Should
this be BYTEA? Is it strongly recommended by the postgresql community to
store things like images in bytea format as of 8.0?

Thanks,
