Let me know if you need any further clarifications from my end.

Did you install delegate libraries for image formats such as jpg, png, etc in the same location before you installed IM?

What do you get from

convert -version

Does it list delegates for jpg, png, etc?

When you install from source, you need to install all the delegates. If you install from binary, IM comes with most delegates preinstalled.

If you have delegates installed, then perhaps IM does not know where they are, so you need to configure with some extra arguments. See
http://www.imagemagick.org/script/advan ... #configure

Output of convert -version

As you see below , i tried doing identify for jpeg file, and it throws an error for PNG format .

It appears that you need to install libpng and other delegates in the same place as where you have libjpg before installing IM.

I tried to install "libpng-1.5.19.tar.xz" on my ubuntu

chan@kpp-qa2-5803:~/softwares/libpng-1.5.19$ ./configure --prefix=/home/chan/softwares/usr/local

chan@kpp-qa2-5803:~/softwares/libpng-1.5.19$ make
make: *** No targets specified and no makefile found. Stop.

chan@kpp-qa2-5803:~/softwares/libpng-1.5.19$ make install
make: *** No rule to make target `install'. Stop.

Any idea, why its not letting me install from libpng source!!
Is there any way i can install all needed delegates in one go? or how do i use binary version of Imagemagick to achieve the same.
My main idea is to install it in a specific path & also i should be able to carry out the folder onto other machines without installing again!!

Sorry I am not an expert on installation on Linux. I use MacPorts to install my delegates on my Mac and then install IM from source.
