One of my users asked if there was a plugin to take automatically a screenshot from a submitted website url. He also asked if there was a wordpress plugin for this.
can anyone tell me if such a plugin exist for wordpress or if it’s possible with php, ajax or any other language?
As far as I understand your question you can use http://wordpress.org/extend/plugins/seekxl-snapr/ this plug-in will show a thumbnail of the url as the mouse over.
There are other plug-ins that uses websnapr[dot]com to create the images as well.
