it helps some times I'm trying to display image in DataGridView control, I used this code: , try this :
Dim request as WebRequest = WebRequest.Create("http://cache.images.globalsportsmedia.com/soccer/teams/75x75/1241.png")
Dim response = request.GetResponse()
Dim responseStream as Stream = response.GetResponseStream()
Dim bitmap2 as Bitmap = new Bitmap(responseStream)

fixed the issue. Will look into that further Hum - maybe you should try setting the links (.menu a) to display: block to have the links working properly. Otherwise the link won't stretch to use the specified size, links are inline elements (correct me if I'm wrong, didn't test it).

like below fixes the issue You need to create a TilePane and add the ImageView's to it. You can have a ScrollPane if needed. A complete example with double click to create a fullscreen preview is shown below. You can of course do necessary changes for creating a FXML :)

'Hover image display image' CSS is not working properly


Tag : html , By : Roel

To fix this issue Use background-size property, as you are setting a background-image property to a:before element and the size of the background image is 256x256. But you've defined the width & height of the a:before element to 50px, so the size of the background image should also be 50px.
Just use:
a:hover:before {
  background-size: 50px; /* as you have 'width' and 'height' defined as 50px each */
}
a {
  position: relative;
  display: inline-block;
}

a:hover:before {
  content: '';
  display: block;
  background-image:url('http://i.imgur.com/fGAbTOj.png');
  width: 50px;
  height: 50px;
  background-size: 50px;
  position: absolute;
  top: 0;
  left: 0;
}
