Thank you Danny and I understand exactly what you are saying. This plugin does work without the captions so I am just going to have this type of gallery without them.
I have copied 2 styles of posting the gallery which are the 2 option available.
First option is insert a whole gallery using shortcode which produces all the images from the album with captions. The result is only 2 columns
The second option you can select the images you want in the order you want and carries a lot more code. This option also allows you to remove the captions. This does give me what I am looking for but only if i remove the captions. I have updated the problem gallery now using this method.
There is option to include for you to define default class for images from theme's style.css and also to hardcode some css attributes but none of these seem to make any difference.
BTW, I have also contacted the plugin author after your first reply but he is yet to respond.
Thank you once again for your patience and help.
