Please I'm using PHP to generate PDFs.

Everything works like a charm but when I insert bmp images in the PDF I get the following error:

Wed Jul 15 12:46:18 2015: http://dentalhubec.com/wp-content/uploads/2015/05/andramuno.bmp: warning: Unknown image MIME type: image/bmp

Please how can I resolve this?

Hope you can give me a hand in this.

Prince does not support BMP images, so you will need to convert them to PNG or JPEG.
