Pixelated Banners in Drupal

I am having trouble with the banners on this Drupal Site (www.ciob.org.uk) The static banners are somewhat pixelated when viewed in the front end. In the back end they are listed and shown as they would appear. These se开发者_如何学JAVAem fine and have no pixelation.

I also have an issue where the banner is 700x230 on the image info yet when I have uploaded an image it cuts 30 pixels off the right side.

Any help on either of these issues would help.

Thanks

You use Imagecache to process your images. ImageCache will resize all images to the dimensions that are configured in his preset. For your case, 700*230

This is your image proccessed with imagecache : http://www.ciob.org.uk/sites/ciob.org.uk/files/imagecache/700x230sc/images/Skills%20Survey%202011%20Banner_1.jpg

This is the image you uploaded : http://www.ciob.org.uk/sites/ciob.org.uk/files/images/Skills%20Survey%202011%20Banner_1.jpg

Th original image is 680*230 pixel, and imagecache will upscale it to 700 pixel wide, that's also why you loose some content on the right.

You can either :

• Use an Original image with correct dimension (700*230)
• Don't allow imagecache to upscale images (there is an option for that), but you will probably some blank area in the banner, on the front page.
