Code:
count=0

  echo wget -O "$2_img${count}.jpg" $p
  count=$((count+1))
  
done <2

then, with your script I manadge to print all the line of the file,
but then it's does't seem to work to create command

I put echo to debug it but I want to make it part of a comand with wget.

I hope I'm clear enough for you to understand.
Change the:
Code:
  echo wget -O "$2_img${count}.jpg" $p

to:
Code:
  echo wget -O "$2_img$(printf '%04d' "$count").jpg" $p

and get rid of the echo when you are done debugging.

PS If you tell us what operating system and shell you're using, we might also be able to suggest some shell specific shortcuts to do this. Depending on what shell and (and version of that shell) you're using, there might be shortcuts that would run slightly faster, but would be less portable.

git-sh-i18n

GIT-SH-I18N(1)							    Git Manual							    GIT-SH-I18N(1)

NAME

       git-sh-i18n - Git's i18n setup code for shell scripts

SYNOPSIS

       . "$(git --exec-path)/git-sh-i18n"

DESCRIPTION

       This is not a command the end user would want to run. Ever. This documentation is meant for people who are studying the Porcelain-ish
       scripts and/or are writing new ones.

       The 'git sh-i18n scriptlet is designed to be sourced (using .) by Git's porcelain programs implemented in shell script. It provides
       wrappers for the GNU gettext and eval_gettext functions accessible through the gettext.sh script, and provides pass-through fallbacks on
       systems without GNU gettext.

FUNCTIONS

       gettext
	   Currently a dummy fall-through function implemented as a wrapper around printf(1). Will be replaced by a real gettext implementation in
	   a later version.

       eval_gettext
	   Currently a dummy fall-through function implemented as a wrapper around printf(1) with variables expanded by the git-sh-
	   i18n--envsubst(1) helper. Will be replaced by a real gettext implementation in a later version.

GIT

       Part of the git(1) suite
