This shouldn't actually be happening. I'm wondering if something is strange with either the source server or the server your site is on?

Would you mind providing an example of a source URL that, when imported into concrete5, shows up funny? They should do their best to keep the original filename.

just curious, how do you upload files by URL?

File manager click on the "More" link on the top right of the box and click on the "Add Remote Files" tab enter an url and press on the add files button

Tried URL, get wierd response that the file extension is wrong! Why would I get a file extension error if I'm just putting in a URL?

Hi
I cannot get this feature to work, I noticed a thread in the bug tracker that blamed iconv not being installed but my phpinfo reports

iconv
iconv support enabled
iconv implementation glibc
iconv library version 2.5

Directive Local Value Master Value
iconv.input_encoding ISO-8859-1 ISO-8859-1
iconv.internal_encoding ISO-8859-1 ISO-8859-1
iconv.output_encoding ISO-8859-1 ISO-8859-1

and it shows in my environment variables list on the dashboard.
When i try to add remote files the page loads for a second but nothing happens and the file dialog remains on the screen?

Any thoughts?

Are you getting any error messages at all or is this just failing quietly?

Its just failing quietly, the dialog doesn't close and nothing appears to happen.

Have you looked to see if you are getting any javascript errors in something like Firebug for Firefox? Sometimes it will look like nothing is happening when you are getting javascript errors. Also, are you sure the data is a direct link, imgur.com is probably the easiest thing to link to for testing. Just get any image URL from there and try to upload that.
