hello. I'm using the latest verson of NexGen gallery and ran the "Plugin Check" feature to ensure everything is set properly. It passed on the first two tests but showed a warning on the third:
1) Check plugin/theme conflict
No conflict could be detected
2) Test image function
Could create image with 3072 x 2304 pixel
3) failed Check theme compatibility
Missing the call to wp_head() in your theme, contact the theme author <<<<<br /> Do you have any suggestions on how to resolve this issue?
Although i personally don't use nextgen, it works fine with Striking. If you go to the 3rd party plugins category, you can see some threads on using the plugin with Striking.
One thing you will need to do is wrap the nextgen shortcodes in the raw tag, which Striking supports. The raw tag tells the theme to parse the nextgen code uninterrupted. Usage with the raw tag would be as follows:
[raw] [nextgen code] [/raw]
Note that there is a space between tags. Keep that space. Don't have the brackets butt up against each other.
