Remove specific element from the list

How can I remove each element(picture) from the list that has a Tag value smaller than a Tag value from some another picture, in my case selectedPicture. It doesn't allow me to use <= operator saying

Operator "<=" cannot be applied to operands of type "object" and "object".

Here is what I did:

pictureBoxList = pictureBoxList
  .Where(picture => picture.Tag <= selectedPicture.Tag)
  .ToList();

As the error suggests you can't use <= to compare objects. You need to cast Tag property depending on what's the underlying type. For example if it's int:

.Where(picture => (int)picture.Tag <= (int)selectedPicture.Tag)
