Dynamic Content Gallery Review
Features
Dynamic Content Gallery’s auto image management option is a feature unique to all slideshow plugins. It automatically pulls image attachments from relevant posts or pages. Using WP’s post thumbnail feature, this plugin can also generate auto carousel thumbnail. It also uses the latest version of mootools (1.2.4).
Usability
It has user settings for image file management with the corresponding JavaScript and CSS options. An error message reporting also makes your life easier with its built-in configuration and validation checks. To install this plugin, download its latest version, Dynamic Content Gallery version 3.3.5.
While extracting and uploading the files, you need to ensure that you do not change any filename to avoid further errors. You can now activate the plugin in your dashboard after uploading. To configure your settings, go to the setting’s page.
Only minimal bugs and errors are reported by users. Others are very satisfied with their new dynamic plugin which saves them a lot of time because of its automatic image pulling feature.

Conclusion
There are 4 options of populating the gallery which gives it a head start among other plugins. It is more flexible in terms of functionality and can really suite your style.

Installed this plugin on my company blogs. It takes a little time to know what you are doing. After that you can customize it perfectly and have a nice slideshow whereever you want.
I have used many dynamic content plugin and this is the best so far.
