Image Location in FireFox Help Needed

[UncleJohnsBand]

I guess what I was looking for was not having to have the UNC in the URL at all. What I was suggesting was a virtual directory for the images. I don't think cassini itself has built in support for this, but there is an enhanced version called CassiniEx which does support virtual directories.

The advantage is that if I wanted to access my pictures from a computer that didn't have access to the network drive to view them, then the image can be viewed as if it were just in another directory on the existing web server. To me, changing the way FireFox has it's default preferences setup just to be able to access an image isn't the correct way to address the problem. It's a short cut method. A couple of different ways would be to either:

1. Have the images directory physically under the gbpvr webserver directory. (Not the recommended way)

2. Have the site wrap the UNC so that it isn't included in the URL or as a file:/// option. The script it self would access the files to be displayed, but it would appear to be as a http:// request instead of a file request. Again, I'm not familiar enough with the .Net control you are using to do this, and it may mean more work than just using an existing control to do it. However, I think it keeps the access method browser independent, and doesn't have people change their security settings or configuration files.

I just don't like the idea of having people to mess around with their configuration settings, to get it to work on a different browser when their are ways to get it to work without changing browser settings.

I agree....not sure why FireFox incorpoerated this Security Policy. It started in version 1.5. The Security Policy is what is forcing this config change....the browser itself can handle it.....it just isn't natively allowed to do so.

Just to note the file:/// does not show up anywhere in the url....you have to either view page source or right-click on the image and show the properties to see it.

Here is the URL that shows up in the Photo page that displays the image:

Code:

http://den:7647/gbpvr/Photo.aspx?pic=_wEFRFxcTmFzbGl0ZS1zbWJnXERpc2stNFxQaWN0dXJlc1xCYWx0aW1vcmUgMjAwM1xCYWx0aW1vcmUgMjAwMyAwMDEuanBn

This is what shows up in view page source:

Code:

<img id="picture" class="photo" src="file://///Naslite-smbg/Disk-4/Pictures/Baltimore%202003/Baltimore%202003%20001.jpg" border="0" style="height:480px;width:640px;" />&nbsp;<!-- Topbar end --><tr>

As for the Thumbnails. If an image already has a thumbnail in it why not just stream the thumbnail itself? Maybe I'm misunderstanding that problem.

Thumbnails are just that a thumbnail....they are a picture that my abe 1"x1" max in size....enought o figure out what the picture is. If you then expand this 1"x1" thumbnail to something like 640x480 or 1280x960 you just get a crap picture since the thumbnail has to be scaled up to the new size....which just doesn't work.

Normanr to the rescue.....he gave me an idea that I think we provide all of us what we are looking for......

I'll be back.... :-)

When I'm refering to a URL, I'm referring not to just what shows up at the top of the browser but any link to resource like the following:

Code:

file://///Naslite-smbg/Disk-4/Pictures/Baltimore%202003/Baltimore%202003%20001.jpg"

So, that is why FireFox is having the problem, it's the added (and rightfully so) security it has for file access. Again, as Sub and I have both said, this option should really be replaced with an ASPX script that is called from the server.

Looking forward to seeing the new approach.

Ok....new apprach is using what was already coded into EWA for displaying images from the file system. Normanr added it when we added channel icons to the guide. The channel icons are using this same image control.

I am now able to set the location of th picture to a serialized path and create a URL for it that utilizes the download.ashx page. This page passes it into backend code that actually streams the image to the browser.

Here is what the new URL of the image looks like:

Code:

http://localhost:7647/gbpvr/Photo.aspx?pic=download.ashx/-6,1?_wEFQ1xcTmFzbGl0ZS1zbWJnXERpc2stNFxQaWN0dXJlc1xDVU1DIEVhc3RlciBCcnVuY2ggMjAwMlxEU0NGMDAwNC5KUEc*

This works perfectly with no browser security changes at all.
