While I'll content storing image blobs isn't my favorite way of doing 
this.. and not all of my tricks work in all browsers or PHP installs. .
Tricks include (this is for a PNG, but can also work for other types)


Cut and pasted:

#works for everything but MSIE < 8 - Oh.. Just 70% of the web. Sure is sexy though.
ob_start(); imagepng($image); $imgdata = ob_get_contents(); 
ob_end_clean(); $img = base64_encode($imgdata); imagedestroy($image);
print "<img border=\"0\" src=\"data:image/png;base64," . htmlentities($img) . "\" alt=\"embedded graph\">" ;
