    <p>I'm using an external web service that will return an image URL which i will display in my website, For example :</p> <pre><code>$url = get_from_web_service(); echo '&lt;img url="'.$url.'" /&gt;'; </code></pre> <p>everything is working fine except if i have 100 images to show then calling the web service become time &amp; resources consuming.</p> <pre><code>//the problem foreach($items as $item) { $url = get_from_web_service($item); echo '&lt;img url="'.$url.'" /&gt;'; } </code></pre> <p>So now i'm considering two options:</p> <pre><code>//Option1: Using php get_file_contents(): foreach($items as $item) { echo '&lt;img url="url_to_my_website/get_image.php?id='.$item-&gt;id.'" /&gt;' } get_image.php : $url = get_from_web_service($id); header("Content-Type: image/png"); echo file_get_contents($url); //Option2: Using ajax: echo '&lt;img scr="dummy_image_or_website_logo" data-id="123" /&gt;'; //ajax call to the web service to get the id=123 and get the url then add the src attribute to that image. </code></pre> <p><strong>THOUGHTS</strong></p> <ol> <li>First option seems more straight forward, but my server might be overloaded and involved in every single image request.</li> <li>Second option it's all done by browser &amp; web service so my server is not involved at all. but for each image i'm making 2 calls 1 ajax call to get the image URL and another one one to get the image. so loading time might be vary and ajax calls might fail for large number of calls.</li> </ol> <p><strong>Information</strong></p> <ol> <li>Around 50 Images will be displayed in that page.</li> <li>This service will be used by around a 100 user at a given time.</li> <li>I have no control over the web service so i can't change its functionality and it doesn't accept more than 1 image ID for each call.</li> </ol> <p><strong>My Questions</strong></p> <ol> <li>Any better option i should consider?</li> <li>If not, which option should I follow? and most important why i should follow that one?</li> </ol> <p>Thanks</p>

    2. COYa i already have it installed but do you think a 100 ajax call + a 100 image call is a good idea ? @Drazzi

    3. CO@ra_htial: Nah, not the best idea ever... not at all. Especially since you're not setting any cache-control headers... try keeping the images in a DB, cache them as if your life depended on it, and even then... clients will request those 100 imgs via AJAX calls? why? that's just painful for both client and server

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
