I sorta threw some pseudocode in there to demonstrate what I'm trying to do. . Where I am stuck is, I am trying to read in a list of images. The while/do works fine but I get confused as to how to represent all the images in the list as a single item such as '$image' because I need to scale all of them and them spit them back out on the command line with new names by adding -thumb to their names. Also I'm trying to make it JPG specific meaning if the list gets a .html file for example by accident it should skip over it. My biggest problem is I dont know how to represent a list of items as a single variable if that is the right word. Any help just to get started in the right direction is appreciated. . thank you

NAME
img-ps - Img, Adobe PostScript Format (ps)
SYNOPSIS
package require Tk
package require img::ps ?1.3?
image create photo ?name? ?options?
DESCRIPTION
The package img::ps is a sub-package of Img. It can be loaded as a part of the complete Img support, via package require Img, or on its
own, via package require img::ps.
Like all packages of Img it does not provide new commands, but extends the existing Tk command image so that it supports files containing
raster images in the Adobe PostScript Format (ps). More specifically img::ps extends Tk's photo image type.
The name of the new format handler is ps. This handler provides new additional configuration options. See section PostScript OPTIONS for
more detailed explanations.
Note that this package provides a pdf handler too, i.e. a handler for the Adobe Portable Document Format. That handler accepts the same
options as the ps handler.
The package delegates the actual conversion of data in PostScript and PDF format into a raster image to the ghostscript application. It
therefore depends upon the presence of said application and is non-functional is ghostscript is not present.
All of the above means that in a call like
image create photo ?name? ?options?
[1] Image data in ps and PDF format (options -data and -file) is detected automatically.
[2] The format names ps and pdf are recognized by the option -format. In addition the value for the option is treated as list and may
contain any of the special options listed in section PostScript OPTIONS.
PostScript OPTIONS
The handler provides two options, both influencing the reading of PostScript or PDF images. The handler is not able to write images in
PostScript or PDF.
-index n
This option is for reading from PostScript/PDF data containing more than one page. When specified it will read the n'th page in the
data. The first page is at index 0 and will be read by default, i.e. when the option is not specified.
Note: This option is not yet implemented.
-zoom X Y
Multiply image size by the given scale factors. If Y is missing, the default is the same as X. X and Y are allowed to be in floating
point format, but they are rounded to the nearest practically possible value. For postscript this means the zoom factors should be
multiples of 1/72.
REQUIREMENTS
The code provided by Img does not perform the interpretation and rasterizing of the input by itself but delegates this to the gs applica-
tion. This is the GhostScript implementation of PostScript (and PDF).
If gs is not installed this format handler cannot be used.
