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.
