What is a good approach for dealing with the uploading of image sequences

I am implementing the back end for an online store. The store receives new products periodically. Each product comes with a sequence of images for a 3D rotation effect on the w开发者_运维问答ebsite. What is a good approach for uploading these images onto the web store? I'm currently using a web form but uploading each image using a separate upload form element feels like a waste of time. These sequences can have anywhere from 12-50 frames. Any suggestions for a better way?

If you want a minimum amount of change from your current solution you can add the multiple attribute to your file input box, and update your back-end to support it.

You can then select multiple files at once with a modern browser, for instance Firefox 3.6. Try:

<input type="file" multiple=""/>
