I want to write the slackware ISO image to a USB pen drive , so that i can use it to install slackware. Is this possible?
Most of the articles/tutorials talk about installing to a USB pendrive.

I don't think that slackware supports installation from an iso image on a hard drive which is essentially what you want to do. Fedora, mandriva and perhaps others do.

The procedure is to create a boot floppy or a bootable cd from a small iso image which has a mini linux system capable of mounting and reading your hard drive or flash drive. I know mandriva and fedora have specific boot floppy images for a "hard drive installs". When you boot, they ask where the iso is located. They then automatically mount that partition and then mount the iso image and run the install program directly off of the iso.

You have the complicating factor of using a usb mass storage device for your iso image so the kernel on the boot floppy would also have to have the scsi and usb modules built in so as to be able to mount and read such a device. I haven't checked lately, but fedora or mandriva may have floppy image files or small iso images with the drivers you need. However, I've never seen or heard of this type of thing being provided by slackware.

Just curious wouldnt mounting the iso image to local mount point and then copying the content to the pendrive work?

You'd need a modified bootloader (and initrd) to boot the installer from a usb drive.

Umm , would writing the ISO to a CD and then using the 'dd' command to copy files from the CD to USB Pendrive work?

can't we use dd command directly to copy cd image to pendrive like
dd if=*iso of=/dev/sdb1 OR something
