Newbie snapshot file saving question

Question

I want to have Mullesight take a snapshot and place a JPG inside my "snapshots" folder on my desktop. The problem is that it keeps saving the same same file name and won't allow me to take more than one picture. I wish to have successive pictures named differently, such as picture1.jpg, picture2.jpg, etc., in my snapshots folder.
I copied a sample script from Mullesight's author to take a snaphot and save a JPEG file. How can I modify it so that I can do what I want?
Thanks for any help.
try
tell application "MulleSight"
-- save prior state
set shouldScale to should scale
set useSelection to use selection
-- now set what we need
set should scale to false
set use selection to false
-- AppleScript still uses old file/alias magic by default
-- therefore we have to use POSIX
set srcImg to (POSIX path of "/tmp/picture.tiff")
-- save the image as TIFF (other formats are not supported)...
save in srcImg as "tiff"
-- reset prior state
set should scale to shouldScale
set use selection to useSelection
end tell
-- just for the fun of it, convert TIFF into JPEG
set dstImg to (POSIX path of "/tmp/picture.jpg")
tell application "Image Events"
launch
set img to open srcImg
save img as JPEG in file dstImg with icon
close img
end tell
on error errorMsg
display dialog errorMsg
end try

Keep in mind that I do not have an 'iSight' camera.
Code portion that works, which assumes that the 'Picture.tiff' file is saved to current user's 'Desktop' and when converted is saves a 'Picture.jpg' ... 'Picturex.jpg'' where 'x' is 1 or higher in numerical value.
property inc_Value : 0
property file_Name : "Picture"
set desktop_path to ((path to desktop folder from user domain) as string)
set file_Path to (desktop_path & file_Name)
tell application "Finder" to set desktop_List to name of every file of folder desktop_path whose name extension is "jpg"
set newFileName to my handlerepeats(desktopList, "")
try
tell application "Image Events"
launch
set img to open ((file_Path & ".tiff") as alias)
save img as JPEG in file (desktop_path & newFileName & ".jpg") with icon
close img
tell application "Finder" to delete ((file_Path & ".tiff") as alias)
end tell
end try
on handlerepeats(localList, local_Inc)
if (local_List contains (file_Name & local_Inc & ".jpg")) then
set inc_Value to inc_Value + 1
my handlerepeats(localList, (inc_Value as string))
else
set inc_Value to 0
return (file_Name & local_Inc)
end if
end handle_repeats
Total code ...
property inc_Value : 0
property file_Name : "Picture"
set desktop_path to ((path to desktop folder from user domain) as string)
set file_Path to (desktop_path & file_Name)
try
tell application "MulleSight"
-- save prior state
set shouldScale to should scale
set useSelection to use selection
-- now set what we need
set should scale to false
set use selection to false
set srcImg to (file_Path & ".tiff") -- or, you may have to use the next line instead.
-- set srcImg to (POSIX path of (file_Path & ".tiff")) -- use if the above line fails.
-- save the image as TIFF (other formats are not supported)...
save in srcImg as "tiff"
-- reset prior state
set should scale to shouldScale
set use selection to useSelection
end tell
tell application "Finder" to set desktop_List to name of every file of folder desktop_path whose name extension is "jpg"
set newFileName to my handlerepeats(desktopList, "")
try
tell application "Image Events"
launch
set img to open ((file_Path & ".tiff") as alias)
save img as JPEG in file (desktop_path & newFileName & ".jpg") with icon
close img
tell application "Finder" to delete ((file_Path & ".tiff") as alias)
end tell
end try

on handlerepeats(localList, local_Inc)
if (local_List contains (file_Name & local_Inc & ".jpg")) then
set inc_Value to inc_Value + 1
my handlerepeats(localList, (inc_Value as string))
else
set inc_Value to 0
return (file_Name & local_Inc)
