You could use a pseudo element in order to create your speech bubble triangle, as shown in the demo below.
This works by using a skew
on a square, and position it absolute
ly within a relative
ly positioned container element.
Alternatively, this could be achieved with a single element if you were able to use the background-image
instead of an image tag.
.circ {
height: 100px;
width: 100px;
border-radius: 50%;
bordeR: 5px solid tomato;
position: relative;
}
.circ img {
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
border-radius: 50%;
}
.circ:before{
content:"";
position:absolute;
top:10%;
right:0;
height:20px;
width:20px;
background:tomato;
transform:skewX(55deg) skewY(10deg);
}
<div class="circ">
<img src="https://i.stack.imgur.com/lCp2t.png" />
</div>
for more info in generating the triangle, you may find this quite a useful demonstration of how to achieve this triangle.
Background-image
By using a background-image instead, you can make this with only a single element.
.circ {
position: relative;
height: 100px;
width: 100px;
border-radius: 50%;
border: 5px solid tomato;
background:url(https://i.stack.imgur.com/lCp2t.png);
background-size:100% 100%;
}
.circ:before{
content:"";
position:absolute;
top:10%;
right:0;
height:20px;
width:20px;
background:tomato;
transform:skewX(55deg) skewY(10deg);
z-index:-1;
}
<div class="circ"></div>
