The stretched photos are indeed ridiculous - and there's usually a giveaway when you can see e.g. that the bed is significantly wider than it is long.
Making them name the rooms would just lead to dramatic descriptions, making a tiny box room into a 'spacious study', a potting shed into an 'orangery' and a manky, grim, dark garage into a 'character man cave'.
I also hate when they over-egg and massively big up the amenities in the area as well - sometimes with photos - as though they're an exclusive feature of that particular property and not of the whole town.
I agree that 'link attached' would be more accurate and honest. I also don't see why Rightmove couldn't add it as an additional option, so that you can easily add it to or remove it from your filter, depending on whether it matters to you or not.
Nobody is expecting the EAs not to put the most positive perspective on the properties that they're selling, but there is optimism and there is plain old lying.
Why does it help anybody to get people out to view properties without knowing the full facts and with significant hidden negatives? It's just wasting everybody's time. In these days, with the internet and all the details and photos that can be given in advance, actually going to view the house should be the last stage of verifying if it's right for you; not the first stage.
If the price is right, somebody will buy it. As an EA, it's your basic job to find that person, and not to waste everybody's time with the people who certainly won't be buying it, however good it artificially makes your stats look.
