feature request : grab from URL

Hi !
I love your plugin ! I use it since a lot of time and it’s really a must have.
BTW, I have a feature request. Today, I had to replace a lot of images, which were too small. There were an higher resolution on a website I found, and what I am missing in your plugin is a feature allowing to grab a file from an URL :
instead of having to save the image to my desktop, remember its name, then upload it with your plugin (this takes time), I could just copy/paste the url and it would do the job.

I already have the plugin “Grab & Save” which already have this function (but it’s not to replace medias, it’s only to upload it).

Eventually, the option could be enabled if that plugin is activated…

What do u think of it ?
