I have a URL to an image which i want to save locally, so that I can use Paperclip to produce a thumbnail for my application. What's the best way to download and save the image? (I looked into ruby file handling but did not come across anything.)

For Example: i Have my file in SVG folder inside Public Directory. Now we Can Access any file in Public Folder Like below and Pass id and Download option. Download option rename any file which u want to download. Now Click able link is Ready We Can Click on Above link to Download the File.
Plain old Ruby The most popular way to download a file without any dependencies is to use the standard library open-uri . open-uri extends Kernel#open so that it can open URIs as if they were files. We can use this to download an image and then save it as a file.
You need to invoke mspaint.exe with the applicable command line flags. Do note though that I don't believe MSPaint handles JPG files. You'd need to search around google or perhaps submit another question regarding MSPaint and opening files via the command line.
Try this:
require 'open-uri' open('image.png', 'wb') do |file| file << open('http://example.com/image.png').read end If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
