new mod idea about image restriction

[justwondering]

Can anyone create a mod that would disable users abilities to post images via code in there message, but would keep the ability to post graphic smileys? This would be a very usefull feature for the yabbse community - as I`m sure I`m not the only one who has had a board bomabrded with "inapropriate" images. And although aboviously you can bann users, sometimes the image has been there for a while too long before you catch it. Just a thought. Thanks.

Well, you can edit Subs.php and remove the lines (there are 2) that parse [img]...

Thank you for responding, I am kind of new at this whole thing, which lines should i remove for this? also, can i disable flash etc via this method, and if so which lines should i remove for that?

Thanks

Flash is in the mod settings area... you can turn it off already. (it should be off by default.)

Could you tell me please the name of the function which contains these lines?

I forget... I think it's parsecodesmilies or something.  Just serach for a LOT of regular expressions in an array.

Function fixTags?

No, search for this: function doparsecodesmilies

That's what a lot of regex in an array looks like!

Ok, been there. Here you can remove images when a message is displayed on screen, but the image tags are not removed from the message itself. Imo it's impossible to include a statement which makes it possible only to show the image when the message is posted by an admin/GM.

I'd like to add functionality to remove image-tags (including the http-part) before storing a message into the database when a normal user is posting the message. Any idea where to start?

This must be it. Haven't tested it yet. Any comments?

I've tested the code and changed a few things. The updated (and working) code is displayed above.

Add and replace in Subs.php.
