Preventing images and text to be selected

Add this to your style sheet

.selectDisable {
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -o-user-select: none;
    user-select: none;
}

.selectEnable { 
    -webkit-user-select: text;
    -khtml-user-select: text;
    -moz-user-select: text;
    -o-user-select: text;
    user-select: text;
}

Just add the class selectDisable to the element you want to prevent from being selected.

The drag effect occurs on webkit(chrome, safari, opera). It does not happen on Firefox.

Don't this apply to your whole document if you have textual content because then you won't be able to select text, which is not very user-friendly.

You could also prevent dragging by adding another empty div on top of your image with the same selectDisable class.

Here is a working example:

draggable="false" worked for me
