not a good place to discuss the merits and demerits of binary blobs. is it ?
now coming back to the question. Firebug firefox addon, and http live
headers firefox addon will be of help to you in this case.
You have <img src="display_img.php?id=1"> tag(or something similar) i
suppose... try opening that src link in a new browser window. For the
application to work, you should see the picture of the user in the new
window
if there are any php errors in that file, correct them before you proceed.
if you see some arbitrary data(without any php warnings or notices)
but not the image that means you did not set header("Content-type:..')
in display_img.php
>> however with a .png extention to get the browser displaying the picture.
thats not required as long as you have correct Content-type header
