Or at least one I've been bitching about since the dawn of RSS feeds and that is sponsors who love to use images to big for the post area of my 3 column blog.
PapaGMP can attest that this has been a pet peeve of mine for awhile since I know I've let him know how displeased I was a couple of times.
The fix ended up being a simple little CSS addition.
Code:
img {
border: 0;
max-width: 450px;
}
Notice max width sets the maximum horizontal size of the image. Images smaller are unaffected. Those larger are scaled proportionately
Oh and yes, I still do use feeds, just not as blog posts.
