- If you have any pattern, ‘reject-regex = urlregex’ or ‘accept-regex = urlregex’ can be used like in gnu.org/software/wget/manual/wget.html#Recursive-Download .gurkan– gurkan2015-05-11 21:03:57 +00:00Commented May 11, 2015 at 21:03

The Windows equivalent to that sort of for loop is for /L. Syntax is
for /L %%I in (start,step,finish) do (stuff) See help for in a console window for more info. Also, Windows batch variables are evaluated inline. No need to break out of your quotes.
for /L %%I in (0,1,100) do ( wget "http://download/img%%I.png" ) ... will download img0.png through img100.png with no numeric padding.
If the numbers are zero padded, there's an added element to consider -- delayed expansion. Within a for loop, variables are evaluated before the for loop loops. Delaying expansion causes the variables to wait until each iteration to be evaluated. So, zero padding then taking the right-most 3 characters requires something like this:
setlocal enabledelayedexpansion for /L %%I in (0,1,100) do ( set "idx=00%%I" wget "http://download/img!idx:~-3!.png" ) ... which will download img000.png through img100.png.

There are some parameters that can be used with wget including a recursive mode and also extension filter.
Please have a look at here
