Content can not be displayed properly

Question

I just hosted my website and I have a problem displaying some content. On my localhost computer, everything is working without problem. However, on my server, some images and text are not shown. Since it is .Net MVC application, I checked everything from saving into the right folder to DB string if it's empty. The images and the text are there, if you can see on the screenshot they are kind of 'disabled'(there isn't any CSS to do that).

<div class="the-ad">
        <img src="/ads/1/00c72afb-748a-43be-b0f0-91685528c5f9_IMG_0115.JPG" class="the-ad-img" kwr34fah2="">
        <div class="ads-extra-images">
            <img src="/ads/1/adimages/2/e57c3b9a-9423-4ff2-8657-7bda2ecffa63_IMG_0115.JPG" class="the-extra-image condpoz" kwr34fah2="">
            <img src="/ads/1/adimages/2/7126e810-28ca-4156-9618-03d696674b14_181428_1599081225461_5306589_n.jpg" class="the-extra-image condpoz" kwr34fah2="">
        <p class="ad-seller-condition">used</p>
        </div>
        <h3>Laptop Fujitsu</h3>
        <p class="ad-description">Laptop Fujitsu 200GB </p>
    </div>

If I add the website domain + image path manually in the URL, the image will be displayed. The others images across the website are showing right. What can cause such a problem?

Update: I did notice that with every refresh some random code is generating in img url, like kwr34fah2="" in the case above.

I can not believe what was the actual problem... AD BLOCKER ...
