## 説明

For each image uploaded WordPress generates several versions with different sizes.
These images will be inserted
 in the post content using the visual editor selecting
the right format size for the current theme, so that images can be displayed correctly
in the theme layout avoiding the overflow to the sidebars or another elements.

These images are now part of the content, and are harcoded in posts independently
to any change in the design
 or behavior of the blog.

Therefore, when switching your theme to another theme smaller, or the new theme 
is very big respect the old
 layout, may be these images do not fit perfectly with
the new design.

For these cases the purpose of this plugin is the searching in the post content 
of images with the old image sizes
 (that result bad sizes for the current theme)
and replace it for the right image format: thumbnail, medium, large, full or custom
format size.

The process is simple and consists of three steps. The first step is a form to introduce
the width to find, or the
 period between two widths separated by an hyphen (-) 
with max 100 points of difference. Optionally you can enter a custom post type, 
or leave blank for the ‘post’ post type.

In the next step present the coincidence or multiple coincidences for each post,
with the old html code in grey color,
 and in black the replacement, and also the
new image is displayed. For each item there is a checkbox (by default checked) that
you can uncheck if the result is wrong or an exception.

Finally, at the end of the list, a submit button can perform these changes. Before
this final step, is advisable to
 backup your posts table.

## インストール

 2. Activate the plugin through the ‘Plugins’ menu in WordPress
 3. Go to menú Tools > Replace Content Image Size and follow the steps.

## FAQ

  Is this plugin safe for the content of my posts?

Each post that needs to be altered goes through a process of reconstruction that
fragments in chunks the post content
 (it is splitted based in newline character),
replaces img elements and attributes width and height, and finally implodes to join
the fragments and update the posts table. It is possible that an strange error may
occur, and for this reasons we recommend to backup your posts table before launch
de last step of the replacement process.

Thank you for this!!! After switching themes, all my images displayed a blank ‘custom
size,’ showing only the ALT text during the post. Thanks to this plugin, I was able
to convert all images with a width of 1024 to ‘full’ and they’re all good now. Thank
You!

What a simple and effective plugin to get the job done. I was able to replace old
Image Sizes to the New Image sizes with one click. And before changing the sizes,
it gave me preview for all OLD image html tags and the new tags will be… Thank you
so much for the great plugin! Great work Pau Iglesias!

I’ve changed the size of the image on my theme quite a few time. A few plugin allow
you to resize your image, but you have to edit all your post to replace the image
with the new size. I used to do that directly in the SQL database, but this plugin
provides a much better and simpler alternative. This only improvement that I could
suggest would be to display the image not in their full size which end up larger
than my display size. It would be more convenient if the image was scaled down.
