I live in Spain and get the Guardian on my 2nd geneation Kindle, but no pictures, at least in today's edition (jul.15th) though usually the front page has a picture. I also get the New Statesman and The Spectator, but, again, no pictures apart from the cover. I think you can probably continue getting The Guardian while on holiday in Spain if you use the "Manage your Kindle" and change your country , then change it back again when you return. For some reason Kindle material from the UK cannot be purchased in Spain, or I imagine in any other European country. All my UK kindle newpapers and magazines are billed in dollars and sent by whispernet from amazon.com in the USA. Reading the reviews it seeems that the UK source has a fair sprinkling of pictures, but I've no idea why we cannot get the same quality from the USA
I would also like to know the answer to this question, as I travel a lot, both to Spain and other countries. Having the paper delivered daily automatically wherever I may be in the world would be great. But it would be frustrating if only part of the paper was delivered, and annoying to have to change my settings every time I travel. At present, I can read the paper online on my laptop, and it sounds as if this is a better experience than the Kindle edition (as well as being free), though the Kindle version seems to have some advantages, e.g. the paper is downloaded and available for 7 days, articles can be saved, etc.
