Tacking Together Text And Incrementing Integers

I've got a simple script going that parses through looking for files in a certain range of numbers and grabs them with wget, but I'm stuck on one thing. Here's what I need:

I've got two strings, one is a prefix "wget http://website.com/images/image0" and the other is a suffix, ".jpg". I want to sandwich between those two an integer that increments. I've got the loop going fine, I just don't know how to get it to stick together and become a single command inside the loop.

I did know how to do this in Java back in the day, but I'll be buggered if I can get this to work

wget http://website.com/images/image${i}.jpg

wget http://website.com/images/image${i}.jpg
[/b]

Worked a charm, thanks.

If your integers have to be a certain width, then use printf.

wget http://website.com/images/image$(printf "%02d" $i).jpg

The $() construct is bash specific though. If you want to be portable to sh, then use backticks ``.
