Reading image source out of other Page

Copy linkTweet thisAlerts:
Jan 16.2011

Hello,

I’m new here and new to JavaScript. There’s a thing I would need for my website: I want to include an image from an other site. But it’s url is changing every day because the image changes every day.
(That’s the site: [url]http://apod.nasa.gov/apod/[/url])

How can I find out the image url with javascript and show it on my website?

Thanks in advance!

Okuro

@SockwaveJan 16.2011 — You can do this, but maybe you shouldn't? That page has a disclaimer about image permissions:

http://apod.nasa.gov/apod/lib/about_apod.html#srapply

which specifically doesn't allow unlimited reproduction. I admit that it's very unlikely that you will have any legal trouble with this, but it's not considered good form to run other people's content on your site without permission.

@OkuroauthorJan 22.2011 — Hello,

I see, thanks for the tip!

Anyway, how would it work if it was legal? (on other websites...)

Thanks!

But it is not. Period.

Indeed, I referred to other NASA-Websites where the images aren't protected with copyright and everybody is allowed to use them as often and where ever they want if they quote NASA.

Maybe. But inserting in your page an absolute url to a picture which belongs to another domain is not recommended. Don't confound the rights to use a picture with the rights to insert a link to that picture.

You may use a combination AJAX+server-side proxy code. If your server allows PHP, see:

You should rather use a server-side code to load that picture into your domain and use it from your domain. Of course, mentioning who is the owner, and the rest of courtesy, etc.

@rnd_meJan 27.2011 — NASA cannot copyright their images or text: they are a US government agency and as such are banned from holding copyrights by our constitution.

that's why i embed the APOD on the front page of a site i built: http://www.astro.uiuc.edu/


we haven't gotten any cease-and-desist letters yet; not holding my breath.

i used a small asp script to grab the html from the APOD site and sniff out the image url.

Success!
