Image Sizes Manager » FAQ
You are not buying this theme. This is only a preview for Image Sizes Manager WordPress plugin which functions exactly the same on all themes.

I created a new image size but the images on my site are still shown in the old size

You have to regenerate images for the new size (or if you edit a size). It will not happen automatically.
And don’t forget to change the image label to the new one in your theme’s function. Ie: the_post_thumbnail(‘new_size_name’).

Will this plugin slow my site down?

Absolutely not. Your blog will be as fast as if you added custom image sizes via PHP code in functions.php.

Will it work on my theme?

Sure! Image Sizes Manager is 100% compatible with all themes. Please remember that ISM requires WP v3.0 or newer.

How many custom image sizes can I have?

As many as you need. But please remember that each custom image size will take up some space on your server so having 100 custom sizes and thousands of images will require gigabytes of free space.

Why can’t I edit 3rd party sizes?

Because they were created by 3rd party plugins or themes and there’s no way for ISM to know how or where that was done. Try looking for 3rd party sizes in your theme’s functions.php file.

How much time does it take to regenerate custom sizes for 10 images?

There’s no way to predict that because it depends on the original size of each image and server’s speed.
On a “normal” server with images of about 0.5MB it takes only a couple of seconds.

I’m getting errors that some images could not be regenerated

Most common reason for that error is a missing original image file which is needed for generating custom image sizes. Other common issue is the writing privilege on wp-content/uploads folder. Please check if WP can write in that folder and overwrite previous old image files.

Will my server be overloaded while images are being regenerated?

Absolutely not! Images are generated one by one so only one image is being generated at any given time.

Regenerating process hangs for minutes

If your server is very slow and images very big regenerating can take a while. Try raising the TIME_LIMIT_PER_IMAGE restriction which will give you server more time to process each image. You’ll find that constant at the beginning of image-sizes-manager.php file. Default value is 35 seconds.

    I struggle trying to re-size an image I’d like to use for a slider on my homepage it has specific requirements as to what size the original image must be reduced so it looks good in the slides. Will this automatically reduce an image to 1000px × 388px for example without cropping it If I had an original image lets say the size was 2000px x 2400?

    If the slider has a specific image size it needs you can either upload an image with the same w/h ratio – then it’ll be resized. If the ratio is not the same it’ll be resized&cropped.
