A simple browser addon that downloads images from sites. It will soon be released as a Firefox extension, and it's tested against Firefox and Firefox only. I plan to test it in Chrome in the near future.
When possible, it tries to use the download attribute so the image will be automatically downloaded, but it rarely works on Firefox. The problem is that on Firefox Same-Origin is enforced (see bug no. 874009). If you want to see what I mean, try it on Bing and you'll see the image won't open as a new URL, but it will be downloaded.
The icon is based on a vector image by Freepik.
For the moment, it supports these websites:
- Bing: download button on the bottom right.
- Earth View by Google: changed download link inside the menu.
- Dilbert: download link on top of the image.
- GoComics: download button just below the calendar navigation,
or on top of a comic list to download a zip containing every listed comic. (tested on Calvin and Hobbes, should work elsewhere.) - xkcd: download button inside the navigation toolbar.
- Instagram: download button between comment and share buttons. If it doesn't show up, reload the page. It's not perfect, but it kinda works.
If you want img-dl to work on other sites, you can open a ticket or implement it yourself and send a pull request.
Inside the sites folder there's a folder for every supported site. All files needed for a specific files should be there, excepts for libraries, that will be added to a separate folder. If possible, just use plain JS.
Script (and CSS injection) are managed by manifest.json, under content_scripts. Don't add URLs and scripts inside a block already present, but create a new block.
Download links or button should blend well into the page style.
