I'm NOT a programmer or anything such so something like this is a godsend. Ok, i read the reviews that you need to download some application, need it to work with Adobe etc, but for a novice like I, that's not really an issue.
It works well & is simple to use, only problem i can see is when it comes to Yslow, even using the advice given by the app dev, it still flags up as an issue. YES my site does use the stretch to fit option - but again as a novice i know no other way of making the main front page site banner look good :D
Anyway, i like it, i use it & it's ok
