Mount img file system:

mkdir ~/img

mount -t udf filename.img ~/img -o loop

sudo kpartx -a .img # creates /dev/mapper/loop0p1 and /dev/mapper/loop0p2

sudo mount -o rw -t ext4 /dev/mapper/loop0p2 mount_target/

Mounting only one partition in img:

fdisk /path/disk.img

Multiply the start number of the partition with the block size (usually 512Byte) to find the offset

mount -o loop,offset=xxxx /path/disk.img /mnt/disk.img.partition
