If you're looking to Download ChatShare on your Chromebook laptop Then read the following guideline.

A great app for sharing chat conversations with friends. You can capture screenshots of a conversation from any messaging app. Open ChatShare and select the pictures, crop the unnecessary parts and combine them in one picture (one on top of another). Share it with friends. By using the app, you can send the whole conversation in one picture. Currently, you might be sharing 5-10 photos of a certain conversation by sending them separately. Sometimes it can be quite demanding and you can accidentally send something that you did not intend to. In addition, by generating only one picture you can share it easily with more people and it takes less space and time. You can also use the app to capture articles and long pieces of text, graphic data and other things that matter to you. Furthermore, it can be used to combine photos and to make beautiful photo combinations in a single picture.
