They are just RENAMED to GIFs or are they converted to GIFs?

There is no "conversion" from one type to another. The data is stored as binary, and when "displayed" using avatar.php, it adds

Code:

header("Content-type: image/gif");

so your browser will believe it's a gif file. The contents of your jpg are unchanged, just sent to the browser as image/gif so it can be displayed.

They are just renamed to GIF. This also happens (in a roundabout sort of way) with custom avatars stored in the database (they send a content header which describes their content to the browser as 'image/gif')

problem with showthread.php, private.php, announcement.php, admin/functions.php logic.

If there exists a customavatar record for the poster, it works great. But if you deleted all the customavatar table records, there's a problem.

Code:

if ($post[hascustomavatar] and $avatarenabled) {

        if ($usefileavatar) $avatarurl="custom_avatars/avatar$post[userid]_$post[avatarrevision].gif";

        else $avatarurl="avatar.php?userid=$post[userid]";

hascustomavatar is false because customavatar.avatardata is null, therefore, it can never check to see if $usefileavatar is true or not. There needs to be a way of determining if a customavatar that's saved as a file exists for that user. Maybe checking avatarrevision > 0.

Code:

 if ($post[avatarrevision]>0 and $usefileavatar and $avatarenabled) {

             $avatarurl="custom_avatars/avatar$post[userid]_$post[avatarrevision].gif";

            } else {

              if ($post[hascustomavatar] and $avatarenabled) $avatarurl="avatar.php?userid=$post[userid]";

          }

member.php - Also, when a customavatar is deleted or changed to a predefined avatar, the user record needs to be updated to change avatarrevision=0.

Let me know if I am way off base here.

You're right. I'll look into it.

I know you can already do this, but this isn't the way it should be done. Its a pain if users want to change all the time or test new ones out.

As Pfunk pointed out, there was a logic error which occurred if you deleted the contents of your customavatar table...

I did sat in the instructions and in the install script that I did not recommend that you empty the custom avatar table unless you really (really) had a good reason to do so.

In any case, the code is now fixed. Visit the instructions page and make the necessary modifications to member.php - the other files do not need to be altered if you have already hacked them.

If any of your members' avatars are not showing up, simply get them to re-upload their avatar and it will fix itself.
