Using  the Multiple Image Upload feature takes three major steps:

• Prepare your images for upload
• Make a ZIP file with your images
• Upload the ZIP file

Prepare your images for upload

To use this feature, your files must meet the following criteria:

• The images in your ZIP file must be saved in a supported image format. Your Merchant Solutions store supports GIF, JPG, TIFF, and PNG image formats. Image files that exceed values set in the Variables section of Store Editor will be scaled down and converted to the format specified in the Uploaded-img-default-type variable field (GIF, JPG or PNG). If you haven't set a default file format in this field, resized images will be saved as GIF. See Store Editor Variables Overview.
• All image files must either be named according to their ID (for example, id.gif), or their ID and target image property variable name separated by an underscore (for example: id_inset-2.gif). The page ID is the identifier that the store creates for each individual page. Important: A page ID itself cannot include an underscore. Learn more about page IDs.
  When naming your images for your ZIP file, you must know what the page ID of the destination page is. The image names must not contain any embedded directory path information or folders. You may find the ID of any page in your site by navigating to that page in the Advanced Editor and clicking on the Edit button. ID is the first item displayed on the page:
  
• Individual images cannot exceed the following measurements:
  • 2 MB in size.
  • More than 2000 pixels in width or height.
  • 2 million pixels total (width times height).

Make a ZIP file with your images.

1. Download and install WinZip or another ZIP utility (if don't already have one).
2. Create a new folder.
3. Move a copy of your images to the new folder.
4. Rename the images to match the ID of the product they're meant for, followed by the three-letter file extension. For example: if you have an image meant for item ID crafty and it's in JPEG format, that image needs to be named crafty.jpg. You can also name the image the itemID_imageproperty.gif.
5. Right-click on the folder and select Add to ZIP or similar command. This will vary depending on which ZIP utility you're using--see the program's documentation for details.
6. Rename the ZIP file to img.zip. It's important that your ZIP file have exactly this filename.

Now you're ready to upload the ZIP file!

Upload the ZIP file

1. Sign in to your My Services page.
2. Click the Store link.
   
3. Go to Store Editor.
   
4. From the Advanced Editor toolbar, go to Controls.
   
5. Under Functions, click the Multiple Image Upload link.
   
6. Click the Browse button and select the img.zip file.
   
7. Click the Send button.
   
8. Publish when ready.
   

That's all there is to it. Your images will be automatically associated with the products that their filenames match. Note that these changes won't be visible online until you publish your store.

Notes:

• A ZIP file for use with the Multiple Image Upload feature can't contain any embedded directory path information or folders. Refer to the Help section of your ZIP utility for instructions on how to omit this.
• The upper limit on the size of the ZIP file is about 25MB. Some browsers impose a lower limit. If uploading a very large ZIP file doesn't work, try creating two or more ZIP files with images and uploading them separately.
• Although you may import/upload images in bulk, there is no process to export/download images in bulk.
