To upload many images at a time, you will need to create a ZIP (data compression) formatted file and then upload the file to your Store. You may upload ZIP files as often as you wish, but only one ZIP file may be uploaded at a time. Follow the steps below.

Prepare your image files for uploading

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
  
  Yahoo! Store supports GIF, JPG, and PNG image formats. Image files that exceed values set in the Variables section of Store Editor will be sized accordingly and converted to the format specified in the Uploaded-img-default-type variable field (GIF, JPG or PNG). If you have not set a default file format in this field, GIF format will be used for resized images. See Store Editor Variables Overview.
  
  Note: TIFF format is supported, but will be converted to the format set in the Uploaded-img-default-type variable field upon upload. If you have not set a default file format in this field, TIFF files will be converted to GIF format.
  
  
• the filename of each individual image must exactly match the ID of the page it is to be uploaded to. The page ID is the identifier that the Store creates for each individual page.
  
  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 will be the first item displayed on the page.

To create a ZIP file with your images:

1. Download WinZip or another Zip utility program if don't already have such a program.
2. Add the images to the ZIP file. You can do this by finding the image files on your computer, highlight the ones you would like to upload, right mouse click, and select "Add to ZIP." Use "Ctrl+click" if the files are not in order.
3. Rename the image files in your ZIP file to match each image with the correct pageID. The name of each image should be the same as the pageID for the page to which you want the image uploaded. Use the exact same spelling as what is found on the Contents page.
4. Save the ZIP file to your computer.

You are now ready to upload the ZIP file.

To upload the ZIP file:

1. Access the Controls section in your Store Advanced Editor.
2. Click the "Multiple Image Upload" link.
3. Click [Browse] and select your file.
4. Click [Send].
5. Return to the home page and click [Publish].

• any file names that contain spaces or other non-supported characters
• any embedded directory path information or folders. Refer to the Help section of your ZIP program for instructions on not saving directory path information or folders

The upper limit on the size of the ZIP file is about 14MB. 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.

Special note for database users:

If you are using a CSV database to create the items in your Store, the page ID will have been created from your code field. It is important to understand how the Store will create a page ID for your pages from the Code field so you can correctly name your images.

As shown below, the Store can only create IDs that use letters, numbers and hyphens (dashes). While the Code field can use nearly any character, when the ID is created, any character that is not a number, letter or hyphen will be converted to a hyphen in the page ID.
