% assuming you are in the directory of choice
extension = 'jpg'
DF = dir(['*.' extension])
for k = 1:numel(DF)
old_name = DF(k).name
new_name = sprintf('%03d.%s', k, extension)
% movefile(old_name, new_name) % UNCOMMENT WHEN YOU ARE SURE
end

Option 1: Write a script in matlab, debug it to make sure that it does not result in data loss (like overwriting some files by mistake). As you don't have the confidence to write this code on your own, the debug step will have to be thorough.
Option 2: There are gazillion programs on the internet that let you do batch renaming. Personally, I'd use http://www.irfanview.com/ which also lets you do batch renaming and is a pretty decent image viewer.
