Hi there!

I am not a moderator or in any way someone that works there. I am a customer just like you but i thought maybe i could give you some tips.

The css you are looking for is this:

element.style {
border-radius: 50px;
}

The element.style needs to be changed to the img you want to do it to.

if you would use:

img {
border-radius: 50px;
}

It should work on all images.
You might need the !important code to overrule things.

img {
border-radius: 50px!important;
}

If this does not what you want, some mod can probably look at the problem more closely.

PS; the 50px can be adjusted to how much of a radius you need.
