Seeking resources to help do external image preview (scraping) like FB and subsequent full-size imag

Hi,

Non-technical founder doing some research to try and help point my
developer in the right direction.

Seeking resources or guidance to help generate an image preview from a
link, similar to the one used in Facebook’s UI, and then subsequently
also allow a user to display / grab the full size image of the preview
as well. Not looking to necessarily create a bookmarklet a la
svpply.com or the like, but interested in figuring out a way whereby a
user can enter a link, select the image they want on the page they’ve
linked to, and then have that image added to a post or submission to a
web page.

Any help, guidance, or anything would be greatly appreciated!!

Thank you!

Maybe… I did a project using alexa thumbnail service, but looks like
that got shut down. One article pointed to the above as a replacement.
I’ve never used it though…

you can do this using a simple ajax process.

submit the link via ajax then in the controller, get the html page
through
the HTTP::Net library or use a gem like httparty. Parse the page with
nokogiri and save all the images in an array. Use the array to show the
user the images found on that link.

Hi Jim,

Thanks a ton for your response. Passed the information along…much
appreciated. Think right now just trying to wrestle with how to work
with different images with different aspect ratios coming from a wide
range of sites!

Best,
