Hi Visvanath,

I kind of gathered much about the anonimizing part but then I wondered about the images I thought you wanted to show. So it was about the URL and not about the image, OK.

I still don't get a clear picture of the process as you described it in the opening post, but since you mention the "draftfile" part of the URL I'll start with that, at the risk of saying something already known to you.

When one first creates a resource and uploads an image, that image is saved in a temporary area that Moodle references with the draftfile.php script, like so:

draftfile.php/5/user/draft/143851244/myimage.png

Once the resource is saved, the file is moved to a final area, which Moodle now references with the pluginfile.php script, for example:

pluginfile.php/33/mod_page/content/1/myimage.png

When one returns to edit the resource, Moodle once more moves the file to a temporary area and so we get a new temporary URL:

draftfile.php/5/user/draft/633419734/myimage.png

If the edition is cancelled, nothing happens and the image at the original final area remains there, but if the edition is saved (even if we didn't actually edit anything), then the image is saved to a new final area:

pluginfile.php/33/mod_page/content/3/myimage.png

So, copying these temporary URL and pasting them in another resource or activity will actually cause problems because Moodle now looses track of the file and that's when we get a broken path.

Let's assume that I have a page with an image, I open that page in edit mode and copy the URL of the image, for example:

draftfile.php/5/user/draft/506189592/myimage.png

Now, I cancel this edition and then I go to create a new resource in which I paste the copied URL. Since Moodle had already created a temporary reference path for this particular new edtion, for example:

draftfile.php/5/user/draft/398686834

the reference carried along with the previously copied and pasted URL is actually useless (because it is a temporary number or reference created for a particular editing instance), and so, when the resource is saved Moodle would have expected to have something at the 398686834 path and not at the copied 506189592 one. We now have a broken reference which Moodle references with the brokenfile.php script, like this:

brokenfile.php#/5/user/draft/398686834/myimage.png

I hope this description will help you determine the root of the problem.

This is why at the following post I adviced using the file picker (the recent files option) and not copying the code:
