Hello all,
I am developing programs for image processing. I want to create prototypes in perl however my knowledge of perl scripting is limited. how would I accomplish the following:

You've just loaded a CD's worth of reference images from an outside company. The images follow a naming scheme such as DSCN-1.JPG, DSCN-2.JPG ... DSCN-10.JPG, although the frame numbers may be noncontiguous (i.e., there may be gaps between numbers).

Although the frames were stored in separate directories on the CD-ROM from which they were loaded, all of the frames have now been placed into this directory: 

      /shots/spi/home/pix/out/home_test_v1/misc_bg8

[download]
The structure of the directory you've loaded them into is this: 
/shots/$SHOWNAME/$SHOTNAME/pix/out/$ELEMENTNAME/$RESOLUTION_$COLORSPAC
+E

Your task is to rename the frames in accordance with SPI standard naming conventions. These include:

1. No capital letters in the filenames

2. No dashes allowed in the filenames

3. The images should be re-numbered so that they are a contiguous sequence (i.e. no gaps)

4. Frame numbers need to be padded to four-digits. ie, "1" becomes "0001" This is denoted by the symbol # so a range of 1-240 would read 1-240#.

5. The frames should be renamed to match the directory in which they are placed in the following manner: 

            $ELEMENTNAME_$RESOLUTION_$COLORSPACE.#.$EXTENSION

So, in other words, each frame should become: 
/shots/spi/home/pix/out/home_test_v1/misc_bg8/home_test_v1_misc_bg8.00
+01.jpg
    
/shots/spi/home/pix/out/home_test_v1/misc_bg8/home_test_v1_misc_bg8.00
+02.jpg
    
/shots/spi/home/pix/out/home_test_v1/misc_bg8/home_test_v1_misc_bg8.00
+03.jpg
    ...
    
/shots/spi/home/pix/out/home_test_v1/misc_bg8/home_test_v1_misc_bg8.02
+40.jpg

[download]
However, the incoming frames are part of a series and must be kept in the exact same order as they were when loaded (i.e., the incoming frame with the lowest index will map to `home_test_v1_misc_bg8.0001.jpg', while the second lowest index will map to `home_test_v1_misc_bg8.0002.jpg', and so on).

Please help
