I have over 5000 thumbnail pictures of size 5kb each. I would like to
able to load all 5000 pictures and view 50 per page using
mysql_data_seek(). I would like to know what are the advantages and
disadvantages of using a MySQL blob field rather than reading the
images directly from the file? How does one insert an image into a
blob field?...

CREATE TABLE blob_table
(
id INT UNSIGNED NOT NULL AUTO_INCREMENT,
binary_stuff BLOB,
PRIMARY KEY (id)
);

Hi,
I have a blob field in a mysql database table. I want to copy a blob
from one record to another. I am having trouble transferring the data
via a php variable. Maybe I need to addslashes or convert to Hex or
something. I've tried a few things but can't quite get it. Here is
simplified code.
mysql_select_db($dbname, $connection);
