I've used instapaper for a long time, and it's a better product than Pocket, but it, too, has the problem of missing images sometimes.

If you want to save the entire snapshot of the web page for archival and references purpose, I think zotero is a good choice. But it's not a good read-it-later product.

Another vote for Instapaper vs Pocket. Basic Instapaper allows you to make folders and select to which folder to save, while basic Pocket only gives you a blank, suggestionless space to write tags.
