PHP Link to an image outside the root folder [a href, not img src]

Here is my situation: images are stored outside the root folder. I can access them with an external php file (as it should be), then file_get_contents, then echo, and then img srcit will display perfectly.

I have a thick box installed, and I want this to happen when the user clicks on the image, it will be displayed in a larger size

<a href="img.jpg" class="thickbox"><img src="my_image_processing.php?img=img.jpg" />

I am trying to create a gallery on click. It happens that a thick box appears, but the image does not work. Instead of an image, bar / junk codes appear with black diamonds with a question mark. I assume this is the source code of the image.

How can I output this as an image, not raw code in

<a href> 's

ADDED: I just played a little with him. When I remove the colon class, it actually works a href. It displays the image on the next page. Fortunately, when I attach the thick box classes, it shows the thick box, but it shows the source code

In your example, you use the jpg file directly, it should look something like this:

<a href="my_image_processing.php?img=img.jpg" class="thickbox"><img src="my_image_processing.php?img=img.jpg" />

That is, a php page that reads a hidden folder and returns an image.

Try:

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

If you see the raw image data as text, your browser may not recognize the output as an image. You can signal the correct mime type using the title bar above.

Thickbox , , , , . . , :

  • URL- script, . URL my_image_processing/img.jpg my_image_processing.php?img=img.jpg ( "mod_rewrite" ),
  • ThickBox ( , - )
  • , , ( script , ),

, Thickbox , , , - vbence - mime , script: "Content-Type".

EDIT:

var baseURL;
 if(url.indexOf("?")!==-1){ //ff there is a query string involved
  baseURL = url.substr(0, url.indexOf("?"));
 }else{ 
     baseURL = url;
 }

 var urlString = /\.jpg$|\.jpeg$|\.png$|\.gif$|\.bmp$/;
 var urlType = baseURL.toLowerCase().match(urlString);
if(urlType == '.jpg' || urlType == '.jpeg' || urlType == '.png' || urlType == '.gif' || urlType == '.bmp'){//code to show images

, ( "php" ), script, .

EDIT2:

If you go to the "change plugin" option, there is an alternative ( ColorBox ) that allows you to make decisions without having to dig into the code, whether the * .php link should be considered as an image. Just find the option photoin the documentation (when set photo=trueshould behave as you expected).

You probably neglected the http headers to display the image.

header("Content-type: image/jpeg");
header("Content-Disposition: attachment;");
