Generate thumbnail images

[ashishrevar]

I want to code one PHP script which allows me to generate thumbs of given images with specified dimensions and names as per Next-Gen Gallery Plugin of Wordpress.

 

I have website for cover pages: http://facebook4free.com/

 

Thumb Gallery Page: http://facebook4free.com/category/facebook-cover-pages/abstract-facebook-cover-pages-facebook-cover-pages/

 

Main Image Page: http://facebook4free.com/abstract-cover-pages-for-facebook-profile-2/facebook-images/image/1-cover-photo-82140/

 

Issue is timeout when I upload images in wordpress plugin. It uploads images in create their thumbs but when I upload more than 10 images it fails. So I want to separately create PHP script which create thumbnails of my FB cover pages with given dimensions and specified name (a pattern).

Many of the images are in .jpg, .png formats but all are having dimensions of 851x315.

Any help would be appreciated.
