Image Attributes Pro already comes with a range of common special characters that you can remove from the image filename to generate image attributes like alt text and image title.
Here is a screenshot of the available
Filter Settings from the
Bulk Updater Settings tab of Image Attributes Pro:
Right below the available filters you have the
Custom Filter and in this doc we will see how to use them to generate the attributes that we want.
Custom Filter And Regex Filter
The custom filter can be used to filter out any characters or words. Words or characters can be comma separated and are case sensitive.
Advanced users can use the regular expression (regex) part of the custom filter to filter out patterns from the image filename before it’s used as an image attribute.
Let’s say you are a photographer and all your images are named in this format:
An example of that would be:
You want to generate the image attribute as:
Lion Walking Towards Sunset
Here are the settings to select in the
Bulk Updater Settings tab.
- To remove the hyphens select
Remove hyphens ( - ) from filenamein
- There is a filter setting to remove numbers. However since all images have a pattern, it’s better to use the
regex filter. (I tested it with the help of regex101.com)
- Select the appropriate
Capitalization Settingsas you see fit.
This is what the settings will look like:

Using Custom Filters For New Uploads
You can use the exact same filters for any new upload to the website. The
Filter Settings for new uploads is split between
Basic tab and
Advanced tab of Image Attributes Pro. Every setting you used in
Bulk Updater Settings is available there as well.
If you want even more customization, you can use the iaffpro_image_attributes WordPress filter to customize the attributes.
Always make a database backup before you begin and use the
Test Bulk Updater button to see if you like the results before you update the entire website.
