# thumbnail problems!

 * when i upload an image i have the choice of cropping it for thumbnail use.
    I
   crop it at 150×150 and it doesn’t get saved. i think its because a 150×150 has
   already been created because my loop calls for post_thumbnail(‘thumbnail’);
 * the only way to get it to save my version is to make a crop at 151×151 and then
   it makes a 3rd file.
 * why can’t it just save over the old thumbnail version?

 * so… can I bump?
 * what I want basically is if I upload a picture for my featured posts at 300×200
   
   I should be able to decide how it crops it for the 150×150 thumbs for the regular
   posts. not it doing it automatically and terribly

 * Shamai – you are not very clear. I take it you want to have two thumbnail sizes–
   one for the featured image and other remaining at 150×150.
 * First open up your themes function file and find where the the thumbnail size
   is set. Something like this:
 *     ```
       if ( function_exists( 'add_theme_support' ) ) {
       	add_theme_support( 'post-thumbnails' );
       }
       ```
   
 * If already not added add this:
 * `set_post_thumbnail_size( 150, 150, false);`
 * Also:
 * add_image_size( ‘featured_thumb’, 300, 200);
 * Then go to where your loop is calling the thumbnail:
 * and replace it with – something like:
 * `the_post_thumbnail('featured_thumb');`
 * —
 * Also you can set the general post thumbnail size from settings > media

 * I was using the_post_thumbnail(‘thumbnail’)
    and I set it in settings > media
   to 150px
 * I also am using the_post_thumbnail(‘medium’) for my featured.
    But when i upload
   an image at 300 by 200, it automatically makes a shrunk version of my original
   to use as a thumb. and I want to be able to override it and crop it my own way
   for the thumb.

 * here is my website
    [http://www.baseshamai.com/blog](http://www.baseshamai.com/blog)
 * notice the featured image is 300×200
    if you click the posts you will see it 
   as thumbnail size -except its not right. its smaller than thumbnail size. under
   media settings I set it to be 150×150 with crop turned on.
 * what am I doing wrong for this not to work?

 * it automatically takes my 300px by 200px and creates a 150px by 100px.
    its not
   cropping and I can’t override the crop when editing the image in wordpress under
   library

 * ok so i found that 300×200 is just not cropping well into 150px it somehow doesn’t
   get cropped.
 * but if I upload a larger image it does get cropped? and the result is a thumbnail
   at 150px
 * if I crop for thumbnail it creates a new file and doesn’t overwrite the original
   thumbnail which is annoying and I end up with 3 files

 * i discovered a problem i think.
    I had two thumbnail sizes. thumbnail and medium.
   I was uploading images at a perfect medium size so it wasn’t auto creating the
   medium size and I thinks somehow this affected the thumb size which was created
   uncropped.
 * i got rid of the medium size and now it created a good cropped thumbnail.
 * what sucks is that I can’t really overwrite that thumbnail, I can only create
   another one.
    if I do that I end up having 3 files in my uploads folder and of
   course int he library you only see one.
