PHP mySQL image blobs

Rob
Ummm...I'm a little stuck on how to approach the following....

I have a mySQL table holding images (fields are: data (blob), name (text),
type (text), size(text), desc (text) )

If I want to show the image on a page (they're all jpg's), how do I do I
implement this?

Uploading, downloading, text listing it is easy...I'm just wondering how I
SHOW it. :-)

I'm completely brain-frozen on this.

Thanks in advance,
Robert

just print them:
header ("Content-type: image/jpeg");
$sql="select blobfield from table where ...";
$result=mysql_q uery($sql,$conn );
$img=mysql_fetc h_row($result);
print $img[0];

header("Content-type: image/jpeg");
echo image blob;
exit;

<!-- surrounding html -->
<IMG src="image_gett ing_script.php? image=whatever" >
<!-- and some more -->

are you concerned about having a "separate" script for the image
getting?
don't need a separate script... your page-generating script could only
output the image when given certain paramaters...

Yes, but how would one do it in the context of surrounding it with an
html page, and not just the image itself?

BK answered your question (twice), but there's another possible answer
depending on your delivery context. If you're serving pages over WWW,
just use the "img" tag to point to your PHP script that prints the image
(like BK said). However, if you're using PHP to generate a MIME
encoded document (such as an email), you can also put the image data in
the HTML tag (so people aren't requesting a document on your server
every time they open that email message). If you are, in fact, creating
a MIME document, have a look at this article that has really good info
on MIME formats:

Thanks Zac!

Actually, thank you everyone. Just for reference, phpbuilder has another
article for showing images directly from a db, including the PHP scripts...

http://www.phpbuilder.com/columns/fl...14.php3?page=1

But the MIME one you showed was also useful (for another project)

Hello -- I'm having a heck of a time grabbing a blob ( a jpeg image) from a mySQL database and displaying it on a page. I am able to connect to the database and retrieve the data, however when the page loads, it just spews the binary garbage rather than displaying the image. Here's the code:
