gifster is a free Chrome extension developed by DerekJonesCanada. It falls under the category of Browsers and the subcategory of Add-ons & Tools. With gifster, users can easily bookmark and share their favorite images on the web.

The extension allows users to bookmark images by simply right-clicking on an image and selecting the "Bookmark image" gifster option. This saves the image to the user's personal library for later use. To browse the library, users can right-click on a text field, such as a comment box, and select the "Insert image" gifster option. They can then scroll through their image library to find the desired image.

Sharing images is made simple with gifster. Users can click the green checkmark to copy the link for the chosen image and paste it wherever they want to share it. Managing the library is also convenient, as users can remove images by clicking the trash can icon, permanently deleting them from the library.

gifster does not store images on the user's computer, instead, it stores text URLs using Chrome's local storage. Additionally, viewing images in gifster's library does not consume extra bandwidth, as web browsers use caching to avoid downloading data that has already been received.

It is important to note that gifster requires access to the user's data on websites, tabs, and browsing activity. However, the extension does not have adware, malware, or spyware, and it does not collect or use the user's data.
