Thanks for your reply re image size.

My own personal view on size would be dependant on the content of the image and the default resolution of the PC screen.  My own screen is 1920 x 1080

Most of the images on The Birmingham SME site, are of mechanical items and being able to zoom into the fine detail is most useful.

If you need to limit all images to a particular size, then 1280 x 1024 would I think be more desirable.

I think what we are aiming for, is the ability to show an image full screen if so desired.

Incidently how has the example site, been able to set their images to 800 x 600 max?

I note also, the the final image size does depend largely on the image file size uploaded to the site. I've just had to change a couple of ours, as when viewed full size the image was still very small.

Best regards.
