text overlay on hover in the image block card

Hi!

I am a bit inexperienced with Sqaurespace so all help is appreciated.

I am using the module in "headlines":

And I would like a text overlay with hover on the image, for photo crediting.

However, I have only managed to get the hover, no text to work...

This is the code I have used. Can anyone tell me what it is missing to get the "filenaame" to appear on hover?

/* Hover Effect Images */
.sqs-block-image:hover { brightness: 100%; transition: .6s; cursor: pointer;}
.sqs-block-image:hover img { filter: brightness(0.9); transition: .3s;}
.image-filename.sqs-dynamic-text {
  font-size: 15px !important;
  }
.sqs-block-image:not(:hover) 
.image-card-wrapper { display:none;}

Thanx!
