As designed XenForo_Upload::_checkImageState

[xf_phantom]

If i'm using

if ($uploadpath)
        {
            $file = XenForo_Upload::getUploadedFile('upload_file');

            if ($file)
            {
                $file->setConstraints(array('height' => 32, 'width' => 32));

                if ($file->isImage() AND $file->isValid())
                {

in my addon and i'm uploading a bmp, $file->isImage() won't be true because of you extension check.

Any reason why bmp isn't included here?

It may be just an oversight. Or it may be just because no one uses BMP files any more.

Or it may be just because no one uses BMP files any more.

Then i wouldn't have run into the problem

 

[Chris D]

Well, clearly someone does use BMP files still, therefore why I said it could be an oversight

But - why use a BMP file?

Can you use another file format?

 

[Biker]

Bit map files tend to be overly huge, and as Chris said it's not a format that's widely used any more.

Tiff is an image format but we don't include that either.

It only handles "web format" images intentionally.
