in a relational database, it would be far better to store that sort of
thing as a table, so you can use relational operations on it.
your example structure would fit nicely into a table like...
CREATE TABLE images (
id integer primary key,
base64 text,
image_type text,
width integer,
height integer,
mime text );
and use a view to construct the html_width_height value as it contains
redundant data
CREATE VIEW images_html (id, html_width_height)
as select id, 'width="'||cast(width as text)||'"
height="'||cast(height as text)||'"' from images;
btw, if that base64 field is in fact the binary image, I would instead
change that to `image bytea` and store the image in binary.
