Nope, I'm not writing to a USB stick. This is the text displayed for the whole operation in the terminal:

Code:

$ dd if=/dev/zero of=myimage.img bs=512 count=2880
2880+0 records in
2880+0 records out
1474560 bytes (1.5 MB) copied, 0.0334915 s, 44.0 MB/s
$ mke2fs myimage.img
mke2fs 1.41.4 (27-Jan-2009)
myimage.img is not a block special device.
$ Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=1024 (log=0)
Fragment size=1024 (log=0)
184 inodes, 1440 blocks
72 blocks (5.00%) reserved for the super user
First data block=1
Maximum filesystem blocks=1572864
1 block group
8192 blocks per group, 8192 fragments per group
184 inodes per group

Writing inode tables: done                            
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 27 mounts or
180 days, whichever comes first.  Use tune2fs -c or -i to override.
$ mount -o loop myimage.img /media/mount_point
$ cp -aR /home/neur0n/Desktop/image_files/* /media/mount_point
$ umount /media/mount_point
$

After this I use archive mounter to mount the image file. I tried using the mount command but it showed something about not being able to find the image file in /etc/fstab or in /etc/mtab

here is the finished file: myimage.zip

dumpe2fs

DUMPE2FS(8)                                                   System Manager's Manual                                                  DUMPE2FS(8)

NAME

       dumpe2fs - dump ext2/ext3/ext4 filesystem information

SYNOPSIS

       dumpe2fs [ -bfghixV ] [ -o superblock=superblock ] [ -o blocksize=blocksize ] device

DESCRIPTION

       dumpe2fs prints the super block and blocks group information for the filesystem present on device.

       Note: When used with a mounted filesystem, the printed information may be old or inconsistent.

OPTIONS

       -b     print the blocks which are reserved as bad in the filesystem.

       -o superblock=superblock
              use  the  block  superblock  when  examining the filesystem.  This option is not usually needed except by a filesystem wizard who is
              examining the remains of a very badly corrupted filesystem.

       -o blocksize=blocksize
              use blocks of blocksize bytes when examining the filesystem.  This option is not usually needed except by a filesystem wizard who is
              examining the remains of a very badly corrupted filesystem.

       -f     force  dumpe2fs to display a filesystem even though it may have some filesystem feature flags which dumpe2fs may not understand (and
              which can cause some of dumpe2fs's display to be suspect).

       -g     display the group descriptor information in a machine readable colon-separated value format.  The fields  displayed  are  the  group
              number;  the number of the first block in the group; the superblock location (or -1 if not present); the range of blocks used by the
              group descriptors (or -1 if not present); the block bitmap location; the inode bitmap location; and the range of blocks used by  the
              inode table.

       -h     only display the superblock information and not any of the block group descriptor detail information.

       -i     display the filesystem data from an image file created by e2image, using device as the pathname to the image file.

       -x     print the detailed group information block numbers in hexadecimal format

       -V     print the version number of dumpe2fs and exit.

BUGS

       You need to know the physical filesystem structure to understand the output.
