 * I want to dynamicaly update this function – add_image_size() when value of this
   variable ( $image_size ) is changed, as in example below. I can achieve that 
   with ‘Regenerate Thumbnails’ plugin, but I want to do without that.
 *  ` if ( $image_size === ‘200×200’ ) {
    add_image_size( ‘portfolio-isotope-200
   ×200’, 200,200,true ); } elseif ( $image_size === ‘700×700’ ) { add_image_size(‘
   portfolio-isotope-700×700’, 700,700, true ); } `

 * Are you sure you really want to do this? For each image size added, WP will start
   creating images of that size for EVERY image uploaded. I could imagine this sort
   of code could end up registering dozens (or more) of image sizes (unless you 
   very carefully limit image sises uploaded).
 * Eventually, for every upload, there could be hundreds of copies of various sizes
   created each time. If you explain what you are trying to achieve, perhaps someone
   could suggest a better approach.

 * I know that, but in my case it not problem for my project, its hard to explain
   why it not problem, but if you can help please help 🙂
