How to store images in chrome extension? - google-chrome-extension

I am trying store the og images and the apple-touch-icons of the websites in my chrome extension. Is there a way I can do that? I don't want to store their URLs because I don't want the users to download them every time.

Creating preview image/thumbnail of url in Node/Express

I'm wondering if anyone had experience creating a thumbnail-like preview of pdfs without saving images in a db. I'm storing url links to music pdfs and am trying to create a small preview of the pages so that clients can see some of the first page of the music in advance. I'm looking to see if it's possible without saving images of the page in the db and instead generate the preview on the page load.

I have an extension in Chrome Webstore I would like to download original files that used to be uploaded. Is there any direct way to download it straight from the store, since I am the creator and I do have access to my account?
You can download the current / past version of an extension on https://chrome-stats.com/. You can also just inspect the source code directly on that website.

How to change images in a chrome extension dynamically?

I'm working on a chrome extension and I want it to change images everyday. How is it possible after I've published the extension? as in, do I have to update it with different images everytime?
You will need to host the image somewhere the extension can access. Preferably with CORS enabled, or you'll potentially run into issues.
It's important to only request it once and then somehow save it on your side (for example, as a data URI that you can store in chrome.storage).

How to make an offline browser on ios?

I need to make an offline browser on ios, which should persistent the specified webpages to the disk with the media resource such as image,css,js. At the same time, the offline browser should be able to download mutiple levels of the website automaticly, for example, make it download the webpage and all the pages linked in this webpage.

uploading data from localstorage to google drive in a chrome extension

Integrating a chrome extension(not hosted) with google drive seems to be not possible if I am correct. Is there a way to upload content from 'localstorage to google drive in a chrome extension?
Can the depreciated documents list api be used to do that? if yes, how?
For example, user has some data in the localstorage of the popup.html page in the extension. User would want to backup that data in his google drive. How can it be done from a chrome extension with no hosted page.
Thanks in advance.
You can upload files to Drive using JavaScript. Check the step-by-step quickstart guide for JavaScript to learn about it, you will have to change the code in order for it to read from localstorage instead of the filesystem:
