Hello Kathleen
Thanks very much, I checked your idea and must say it works nice .... with files, but
when I need pass strings like parameters for PHP program, things become difficult.
I will follow your clever idea, because I know it will work, but first need solve two
problems (sorry I am newer to PHP and sometimes confused the way PHP treat variables ).
First problem is: how store content of image file (jpg or gif) into MySql BLOB fields?
Mysql update command uses variable='value' to update (or insert) values. Image data
has lot of ' " ' and " ' " in between, so I receive 1054 ERROR when trying to pass
update image='$image', because $image variable expands before sending data to database.
Second problem is:
how to pass later same string $image recovered from MySql to display.php3 program?
In your example, your are passing file name, a very single string that wouldn't cause
any confusion, but when passing display.php3?stream-image=$image things will become
hard.
Probably I will need to reopen Mysql database into display.php3 program and so I would
pass only record number to display.php3, letting this program to search again record.
Anyway, I modified display.php3 program to execute $image = fread(file...) and then
echo $image, .... and it works fine.., that's to say, it is just question of string
treatment, and really GD library is not necessary.
Thanks
Miguel
