Custom photo gallery for embedding in OR hosted website and/or blog posts

Would be great to have an option of creating a photo gallery (with image descriptions) to be used on OR hosted website pages, but not the photos of the property. For example, if a user wants to create a photo gallery of local attractions in a blog post or hosted site page. Right now the photos are one by one and besides it is a bit difficult to position them on a page or resize/constrain them with any sort of consistency. They need to be precropped.
