How to show an image from a database with HTML+JS?

I am making a dog shelter app, so I saved all the images URL in the database. So far, this is what I have:

What I want is instead of showing this P I want to show the dog's photo.

My code:

index.html

        <div id="template_especie_show">
            <nav class="navbar navbar-fixed-top df-nav cen col-md-12" role="navigation" style="">
                <ul class="nav navbar-nav" style="width: 100%">
                    <li class="pull-left"><button type="button" id="especie_menu_left" class="btn btn-default btn-menu">Voltar</button></li>
                    <li class="pull-left"><button type="button" id="especie_menu_logout" class="btn btn-default btn-menu-logout">Sair</button></li>
                    <li style="float: none; display: inline-block; position: relative; text-align: center"><a href="#index"><img src="img/icone_ap.png" height="47"></a></li>
                </ul>
            </nav>
            <div class="row vert-offset-top-30"></div>
            <div class="col-md-2"></div>
            <div class="col-md-8">

                <div style="text-align: center"><h2><span id="animal_show_name"></span></h2></div>
                <div class="input-group">
                    <div class="input-group-addon">
                        <span class="glyphicon glyphicon-search" aria-hidden="true"></span>
                    </div>
                    <input type="text" id="table_especie_search" class="form-control" placeholder="Procurar animais">
                </div>
                <table class="table table-hover" id="table_especie">
                    <thead>
                    <tr>
                        <th></th>
                        <th></th>
                    </tr>
                    </thead>
                    <tbody>
                    </tbody>
                </table>
            </div>
            <div class="col-md-2"></div>
        </div>

route.js

                setButton('right', template, 'especie/' + pathArray[1] + '/edit', 'redirect', null);


                var params = 'filter=id_especie%3D' + pathArray[1] + '&fields=nome_especie';
                $.api.getRecords('especie', params, getToken('token'), populateEspecieShowName);

                params = 'filter=especie_id_especie%3D' + pathArray[1] + '&fields=nome_animal, notas_animal';
                $.api.getRecords('animal', params, getToken('token'), populateEspecieTable);

                break;

Thanks everyone for the attention and help!

Solution

I don't know how your data is structured, but you would need a url for each dog in the shelter.

[{"name":"fido", 
"img":"some url"}, 
{"name":"woofer", 
"img":"some 2nd url"}, 
{"name":"champ", 
"img":"some 3rd url"
}]

You would pull that info into your js. Then you would loop over each item and set the image tag source attribute accordingly.

        for(var i = 0; i < arrayOfDogs.length; i++){
         (your img node).src = arrayOfDogs[i].url;         
          }

It looks like you're using jQuery. So you can create a template and when you loop over the data, append a new row/cell/header/whatever to the table or div
