When using open source systems, you can use thousands of features simply by turning them on. You don't have to create the code for the functions you need, just activate them; saving time and money. It's pretty cool stuff. But, the benefit in using open source systems can also be a big challenge when it comes to coordination different aspects of a project. Not everything exists in harmony- even when it is easy to turn on or off- and project planning/development methodologies can mean the difference between reaching your goal and just not.

Any enterprise that requires a fair amount of working with content is a likely candidate for Drupal and because it is so easily extended and flexible there aren’t any real limitations.

I recently was asked to add an image caption to image field on a content type.  I added a field image caption and included it with Alt and Title field.  However, the image field was working fine with Wysiwyg inserted image but not working with the image field.
I started to investigate the problem and I came to conclusion.  But to understand the problem we have to start from the beginning.
