Images not displaying front end after been uploaded in the back end of your magento install. First look at the path of the image to establish if it is been looked for in the cache directory i.e.
/media/catalog/product/cache/1/image/............../d/s
Next check if the image is in the folders following the path without the cache directory i.e
/media/catalog/product/d/s
If the image is there delete the cache folder under .../media/catalog/product/ then recreate
your image should now display
