The Bulk Image Uploader tool allows you to upload multiple product images to your BigCommerce store at once using a ZIP file.
It’s important to note that the Bulk Image Uploader does not replace existing images. If existing images exist, images uploaded via this tool will be added to the existing image set.
The Bulk Image Uploader supports image uploads for both parent and variant.

This support article contains several sections which can be accessed quickly by clicking the appropriate link below:
Upload Images Named By SKU
This option allows you to simply create a ZIP file with your product images named after the product SKU. You can also choose to include an optional CSV with ALT tags and thumbnail settings.
This is the easiest and quickest option to add images to your products. Images added using this method are named after the item’s SKU.
To get started, create a ZIP file containing your product images:
- Images must be named after the item’s SKU. For example, if you have an item or variant with a SKU of WIZ31142, the image to be associated with that item should be named WIZ31142.png (or .gif, .jpg, etc. depending on the image format).
- If you are adding more than one image to an item, simply add a -1, -2, -3, etc to the SKU. For example, if you have three images for SKU WIZ31142 the images must be named WIZ31142-1.png, WIZ31142-2.png, and WIZ31142-3.png (or .gif, .jpg, etc. depending on the image format).
To get started, select the ZIP file containing your images and click Next.

If you want to include a supplemental file with ALT tags and thumbnail settings, you can upload that file here. Otherwise, if you do not want to add ALT tags and thumbnail settings to your images, you can skip this step and simply click Next.
- Important note: BigCommerce does not support ALT text for variant images. Any ALT text entered for a variant SKU will be ignored.
If you choose to include a supplemental file:
- Create a CSV that contains a header row with the following fields:
- SKU: This is the SKU the image will be associated with.
- IMAGE_NAME: This is the name of the image in your ZIP file.
- ALT: The ALT tag for the image.
- THUMB: By setting this to “TRUE” the selected image is the main and thumbnail image. By setting this to “FALSE” the selected image will not be the main or thumbnail image. By default, if you are only uploading one image for the SKU, the image is automatically set as the main and thumbnail.

Once your CSV file is selected, click Next.

If a file has been included, you will need to map your fields:

Map your SKU, Image Name, ALT, and Thumb fields and click Next.
By default, Your Store Tools will email you when your import is complete. If you choose to receive this notification, verify your email address is correct before clicking Submit.

Your images are now uploaded to your store and associated with your products! Once your file is processed, you will receive a notification either by email or in the Your Store Tools Notification Center, which is the “bell” in the upper right corner.
Upload SEO-Friendly Image Names and ALT Tags
This option allows you to create a ZIP file containing images with SEO-friendly names. A supplemental CSV file is required to map the image name to the SKU and also allows you to provide an image ALT tag.
For those who want images to have an SEO-friendly name and an associated ALT Tag, we offer the ability to include a supplemental CSV with this information.
- Important note: BigCommerce does not support ALT text for variant images. Any ALT text entered for a variant SKU will be ignored.
To get started, create a ZIP file containing your product images:
- Images can be named anything such as mens-red-cardigan-sweater.png or red-leather-iphone-case-for-iphone-13.jpg.
- If you are adding more than one image to an item, this is specified via the CSV.
Once your ZIP file is prepared, create the supplemental CSV:
- The CSV must contain a header row with the following fields:
- SKU: This is the SKU the image will be associated with.
- IMAGE_NAME: This is the name of the image in your ZIP file.
- ALT: The ALT tag for the image.
- THUMB: By setting this to “TRUE” the selected image is the main and thumbnail image. By setting this to “FALSE” the selected image will not be the main or thumbnail image. By default, if you are only uploading one image for the SKU, the image is automatically set as the main and thumbnail.

Once both files are prepared, select the ZIP file containing your images and click Next.

Select the CSV file and click Next.

Map your SKU, Image Name, ALT, and Thumb fields and click Next.

By default, Your Store Tools will email you when your import is complete. If you choose to receive this notification, verify your email address is correct before clicking Submit.

Your images are now uploaded to your store and associated with your products! Once your file is processed, you will receive a notification either by email or in the Your Store Tools Notification Center, which is the “bell” in the upper right corner.
