# Incompatible – “wrong” – image size generated

 * The image sizes that RT generates sometimes does not match the original image
   sizes generated by WP’s media library when image was uploaded
 * In the linked post, it has an image tag referencing this image:
    [http://www.williamstewart.me/wordpress/wp-content/uploads/2013/10/20131013-L2009596.jpg](http://www.williamstewart.me/wordpress/wp-content/uploads/2013/10/20131013-L2009596.jpg)
 * The IMG src and srcset images are looking for this image:
    [http://www.williamstewart.me/wordpress/wp-content/uploads/2013/10/20131013-L2009596-620×442.jpg](http://www.williamstewart.me/wordpress/wp-content/uploads/2013/10/20131013-L2009596-620×442.jpg)
 * The 620 size was added by:
    add_image_size( ‘ws-large-620’, 620, 9999 );
 * The size of the image generated by RT when I regenerated it with that image size
   set is:
    [http://www.williamstewart.me/wordpress/wp-content/uploads/2013/10/20131013-L2009596-620×443.jpg](http://www.williamstewart.me/wordpress/wp-content/uploads/2013/10/20131013-L2009596-620×443.jpg)
 * I’ve seen this with quite a few images on my site, and have gone through and 
   manually fixed them, but this is a problem for me – I have alot of images that
   still need to be fixed.
 * Looking at the source image, it has dimensions of: 896×640. Scaling this down
   to a 620 width, gives:
    442.857142857142857
 * So, it looks like the RT plugin is rounding up (which Photoshop does as well):
   
   int(442.857142857142857 + 0.5) gives 443
 * Whereas the original WP upload generates a size by truncating:
    int(442.857142857142857)
   gives 442
 * Because I can’t regenerate the HTML code (the srcset also has the “wrong” image
   size), so the image sizes that the plugin does generate has to be completely 
   compatible with the pre-existing HTML parameters, which is a substantial problem..
 * I’m guessing this is a known issue, and I agree that it is a better behaviour.
   But because I can’t regenerate the HTML now, it is a huge problem for me (I can’t“
   fix” the srcset sizes without being able to do that).
 * Ideally, I would like to be able to regenerate the HTML along with the regeneration
   of the images.
 * Thanks
 * William
