BZFlag Image Submitter

As you all know, BZflag can download textures from the internet to apply to BZFlag maps, making the map more enjoyable. Also, in your downloadaccess.txt file, you can only download textures from bzflag sites by default. This discourages some mapmakers, as they need images on their maps, but do not have the credentials to put them on a bzflag server so that they may be downloaded by every client set to the default downloadaccess configuration.

BZflag Image Submitter

This is where the BZFlag Image Submitter comes in. This is a script that makes it easy for anyone to get their images hosted on , and thus be available to every client with a default downloadaccess file.


The BZFlag Image Submitter scrpit does a few things.

1. You use global login to authenticate yourself.
2. You upload your images to the server.
3. You wait as an admin approves or rejects your image.
4. You will get a notice via e-mail when your image is approved/rejected.
5. You will recieve the URL to your image (if it was accepted).
6. You can use your image in your maps!

Note that you must have the sufficent permissions to upload images.

If you need help with the script, or find a bug, you can tell RPG about it: (email)

Im having problems with this...

What browser are you using?
Can you e-mail me the PNG file?

BZIS uses two ways of validating that an image is a PNG image. First off, it checks the file's extention, it MUST end in .png . ANYTHING ELSE AND IT WON'T BE UPLOADED! This is a security feature to prevent people from uploading malicious files.

The second way is to see what MIME type the browser supplied when uploading the image. This is where I think your error is occuring. You have no direct control over what MIME types are assigned to what types of files, your browser automatically does that. If we find out that you just have a buggy browser, you can still submit your image the old-fashioned way, by e-mailling it to a BZFlag admin.

RPG: You need to allow image/x-png too (browsers like IE uses this mime-type).

Great work!! Can you change the code to send a bzbb pm instead of a email? SOME of us may not have a working email that we are ready to give out.

the email is only sent to the admins, aka ME. so it's not like you are giving it out to anyone who can't go find it if they need it.

you must have a valid e-mail address to use the froums... so it should not be a problem just giving it the e-mail address you have on file for the forums.

it's a field in case you want the notification sent to another address.

How long will it take for somebody to approve or eject it? its been a while and still havnt gotten any response

I get an e-mail when you send it, and if I'm infront of my mail I'll do it right then. If not ( like it's night ) it may wait till the next day.

your images were all jacked up and got denied.

the aproval list is empty as I see it now.

you may want to resubmit them, since I think the bug that jacked your images was fixed.

You might have cookies disabled. The authenticated sessions are handled with PHP's build in session manager, via the $_SESSION variables. IIRC, it uses cookies to store your Session ID, which is necessary for your session. I am not too sure on how PHP's session feature works, but cookies sounds like the logical option.

Could there be a checkbox to replace a previous texture submitted of the same name?

No, and I'll tell you the reason why. is a image hosting website for BZFlag. It is not a file storage site of any kind. It's purpose is to store images used for BZFlag maps. Not being a file server, is not the kind of site that you would expect to be able to "delete" files on. "Deleting" files and then subsequently adding another one in my mind is like filesharing, one version of the file becomes obsolete, the other replaces it. I do not see how images can become obsolete. Images should not be replaced. The only reason I can see for replacing images is if you are 1) Testing your map with images hosted on I.BZ.BZ instead of having the images locally, or 2) people think your images suck and you need to replace them. Number 1 you should be testing your map on your own local machine and make sure that you like all the images before you upload them. Number 2 is understandable and would make a good reason for supporting image deletion on I.BZ.BZ, but due to my first point, I won't add image deletion into the image submit script.

My decision stands until a higher admin knocks it down with a giant baseball bat. In which case I would add in image deletion.

I don't think image replacement should be allowed, because other maps may use your textures.

Seems to work well. When you go to there is nothing there.

but shows stuff. is that a glitch?

Bloody heck, you uploaded a JPEG image! I don't think that passed through my image uploader system... there are three different independent checks to make sure an image is a PNG image. Your image is not being recognized because the system only recognizes PNG images. IIRC, JPG's don't work properly in BZFlag as textures.

Spazzy, RPG:
PHP uses %_SESSIONS like RPG, says, and that uses Cookies, it's just a higher way to look at cookies, and stops... Session attacks...

So make sure cookies are there, empty your cache and try again.
