Can I resell items on Ebay without abusing intellectual property rights?

That's right, the photos are most likely copyrighted and belong to the manufacturer, as does the copy editing describing the products. As a practical matter, there are limited ways to describe some of the these products and your own description may sound a lot like the manufacturer's.

I suggest that you review eBay's guidance on how to comply with its product listing policies:

When you buy an item you are entitled to sell it. What you are not entitled is to use the item's manufacturer logos, trademark, pictures, and anything that you did not acquire.
Your best bet is to take a picture of the item and its box, which may contain the trademark and logo, and write in you own words what you are selling, including the trademark of the item, but you cannot use the fonts of anything belonging to the manufacturer,
