Detailed images on product pages desc.

Hello All,

I want to add images to product description area, (example: - but more than this)

Any addons or features - suggestions for this? Uploading images via panel and resizing automaticly?

I can add images with uploading images to ftp and giving link to desc. area via html or add img button, but thats not the solution for me, we have lots of products and uploading to ftp and adding images as url one by one will be too difficult.
