Problem with BMP extension in image. Attach but not insert.

[pequeno]

Hello in IPS 4.1.19.4 ACP I selectes "allow all filetypes.

When a user insert a jpg, gif, png.. image, the image insert in the post with thumbnail. 

But if the image is .bmp extension, the image thumbnail not appears, and insert as an attachment.

I *think* that's normal behaviour as it was on the 3.x series too, the issue is server side I suspect because GD cannot really handle the image resize for .bmp, ImageMagick can sometimes deal with .bmp extensions.

It would however be worth asking this question in a support ticket if you do not get any more details / answers here about it. I'm not "support staff"
