The first photo shows the preview and the second the way it appears on the web.  The same happens if I use Slider or Default theme. The site is live so I am using Tile theme until I solve this problem.

A second question. Using tile theme is it possible to see the lifhtbox directly on loading the page rather than showing the tiles dirst?

Hi Igor

Thanks for the quick response.

I have done a fresh install of the latest version and did not alter the various settings but this did not solve the problem.  All the images are being compressed. The lightbox for the tiles version works well at  http://www.exeterfestivalchorus.org.uk/index.php/gallery and this uses the same images and renders them properly.

Hi Igor

Great - thank you very much. That's solved it. The slides were picking up another less specific custom css rule ...

.article-content img {    float: left;  border-radius: 0px;  max-width: 50%!important;}

Another problem is that slideshow is not working in the Chrome browser but I'll post separately.
