Replace words with images, in a table, using the search/replace tool

Hello everybody

I have a question:

Is it possible to replace words with images, in a table, using the search/replace tool?

My case:

I have a table with about 9000 articles on about 400 pages. In this table there are words which I like to replace with Logos.

Example: The word "DM" should be the Logo "DM" (.eps). This word is about 1200 times in this table.

Is it possible to replace it automatically?

Thank you very much for your helb.

Kind regards Alex
