There have been several threads lately asking for help in identifying (perceived) tomato problems.
Not sure if anybody has mentioned this link before ...

This particular page shows tomato leaf diseases. Click on one of the other labels on the drawing of the tomato at the top of the page to see other types of diseases, eg fruit problems.
This Cornell University site also has similar pages on other crops - a very useful site.
Thanks for that link. A very useful site, now bookmarked.
