BMP Images

[Boofo]

Here's the code I added to view bmps. In admin/functions.php, I replaced this:

if ($post[attachmentid]!=0 and $post[attachmentvisible]) {
		$post[attachmentextension]=strtolower(getextension($post[filename]));
		if ($post[attachmentextension]=="gif" or $post[attachmentextension]=="jpg" or $post[attachmentextension]=="jpeg" or $post[attachmentextension]=="jpe" or $post[attachmentextension]=="png") {
			if (($viewattachedimages) and ($bbuserinfo[userid]==0 or $bbuserinfo[showimages])) {

with:

if ($post[attachmentid]!=0 and $post[attachmentvisible]) {
		$post[attachmentextension]=strtolower(getextension($post[filename]));
		if ($post[attachmentextension]=="gif" or $post[attachmentextension]=="jpg" or $post[attachmentextension]=="jpeg"
			or $post[attachmentextension]=="jpe" or $post[attachmentextension]=="png" or $post[attachmentextension]=="bmp") {
			if (($viewattachedimages) and ($bbuserinfo[userid]==0 or $bbuserinfo[showimages])) {

and in /root/attachment.php, I replaced:

if ($extension=='gif') {
  header('Content-type: image/gif');
} elseif ($extension=='jpg' or $extension=='jpeg') {
  header('Content-type: image/pjpeg');
} elseif ($extension=='png') {
  header('Content-type: image/png');
} elseif ($extension=='pdf') {
  header('Content-type: application/pdf');
} else {
  header('Content-type: unknown/unknown');
}

with:

if ($extension=='gif') {
  header('Content-type: image/gif');
} elseif ($extension=='jpg' or $extension=='jpeg') {
  header('Content-type: image/pjpeg');
} elseif ($extension=='png') {
  header('Content-type: image/png');
} elseif ($extension=='bmp') {
  header('Content-type: image/bmp');
} elseif ($extension=='pdf') {
  header('Content-type: application/pdf');
} else {
  header('Content-type: unknown/unknown');
}

I know the second part of the code is for viewing bmps online, but I'm not sure what the first part does. It has to do with the attachment editor in some way, but I'm not quite sure what yet.

What I need to know is, do I need to add this anyplace else (like for the private attachments) or will this handle that also? And is there any way to come up with the filesize in the post next to an attachment so the user can decide if they want to wait to view it? I mean, if the filesize is too big and they are on dialup, it might be good to know the size of the file so they can decide if they want to wait for it to download to view.

Also, is there a way to add something like a box as the graphic file is downloading for viewing to let the user know how long it will take? Almost like the downloading box. If anyone can please help me, I would really appreciate it.
