Title: Calling a PHP script from inside an <img src.. in code section
Post by: POPDUM on February 02, 2008, 01:22:55 PM

Hi,

I have to retrieve images stored as BLOBs inside of a MySQL DB, and then display them on a page.

Since these BLOBs need to be preceded by a header, I am trying to use a PHP script to output them on the screen. In my code section, I use a statement like:

echo '<img src="myscript.php?pic_num=2" />'; or echo "<img src=\"myscript.php?pic_num=2\" />";

No image is displayed in either case, and it is no wonder because when I see the image properties, it seems that an attempt is made to display myscript.php itself. Is there any way I can invoke myscript.php?

Or is there someone who has successfully implemented something like what I am trying to do.

Any help will be most appreciated!

You will have to tell the browser that a picture is being sent.

Before sending the image data, do the following in your PHP script.

Quote

header("Content-type: image/png");

(or image/jpg image/gif etc)

That should help.

Cheers,

Ruud

Hi Ruud,

I am sending the content-type header, and it works when I try it from PHP/HTML, without the WB code section. Anyway, I resolved the issue by having the system store the images in files and storing the filenames in MySQL.

Thanks a lot for your help!
