whenever moodle users try to insert a bmp image, They get the following error: "Selected file is not an image. Please select an image!" FIX: in lib/editor/htmlarea/coursefiles.php on line 64, add the following: && params.itype.indexOf("image/bmp") == -1 i.e: change if(params.itype.indexOf("image/gif") == -1 && params.itype.indexOf("image/jpeg") == -1 && params.itype.indexOf("image/png") == -1) { to if(params.itype.indexOf("image/gif") == -1 && params.itype.indexOf("image/jpeg") == -1 && params.itype.indexOf("image/png") == -1 && params.itype.indexOf("image/bmp") == -1) { cheers!
