variable in mysql table

[admin]

I want to put variables in a blob. Lets say I have a story and I want to place images in particular areas of the file. I place $image2 after the first paragraph. The in my php I have:

$image2 = <img src='http://www.phpbuilder.com/board/archive/index.php/image2.jpg'>;

then when I echo that field which is a blob it actually just prints "$image2" within the story rather than showing the image.

any thoughts?

Thanks
