It's not supposed to do that -- something else is going on.

I don't think this is doing what you think it's doing:
Code:
if [[ $MANY == *PhotoFiltre* ]]

Asterisks there won't match against $MANY, they match against files in ./ like you're doing with "*.jpg". If you want a regular expression, bash 3.0 has a =~ regex operator so you can just do if [[ "$MANY" =~ PhotoFiltre ]] and see if it finds PhotoFiltre anywhere in the line. I've wrapped $MANY in quotes there in case it has spaces in it.

Why are you backing up and restoring IFS? I don't see that you're using any commands that care what that special variable's value is.

Change #!/bin/bash to #!/bin/bash -x so it prints lines as it executes them so you can tell where the loop breaks and what it thinks it's doing.

Also,"for file in $(ls *.jpg)" can be more simply rewritten as "for file in *.jpg", no ls needed, no evaluation brackets needed. There's still a limit on the number of arguments however, so this kind of loop isn't appropriate for huge amounts of files.

gst-complete

gst-complete-0.8(1)						   User Commands					       gst-complete-0.8(1)

NAME

       gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines

SYNOPSIS

       complete -Cgst-complete-0.8 gst-launch

       gst-complete [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
       gst-launch command lines.

       You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.

       gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
       complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.

OPTIONS

       The following options are supported by gst-complete-0.8 and gst-complete:

       --help	       Display detailed usage message. You can also use -? to specify this option.

       The following options are supported by gst-complete only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Generating the Registry of Available Plugins by Running gst-compprep

       Run the following command in your .bash_profile or other appropriate place:

       example% complete -C gst-complete-0.8 gst-launch

       Example 2: Running the Wrapper Script and Displaying the Command Name

       example% gst-complete --print
       /usr/bin/gst-complete-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-complete-0.Executable for bash completion for gst-launch

       /usr/bin/gst-complete   Wrapper script that runs the latest installed version of gst-complete-X.X
