I recently switched from com_resize to autothumb.
I needed com_resize because it was cumbersome to train the blog
authors to resize their images -- and it it seemed like the software
should do that repetitive and mindless task. I was thankful when I
discovered com_resize. That said, I had some issues with it.
The autothumb plugin doesn't have the directory issues that I had
with com_resize. But, I did have to change my image specifications
to use double-quotes instead of single quotes, e.g.:
width='350'
needs to now be:
width="350"
