Looking for help with posting drawings

Ahh sorry for the late reply. I don't know much about One Drive so I can't answer that.

Google Drive is basically an online flashdrive provided by Google that allows you to store files online to be accessed from anywhere. It comes with sharing options that allow you to share said files anywhere. If you are using chrome and have a google account (Completely free) on the new tab page there should be a 3x3 grid of squares that allows you to select multiple options such as youtube for easy navigation. One of the options is google drive. You can drag and drop files into it to save them online. Selecting a file and clicking on a button at the top right gives options to share it.

Google Drive is completely free and involves no downloads so long as you have a browser that is compatible (Most are iirc.)

Gyazo is a free downloadable program that allows you to freeze you current screen and choose a section of it to take a picture of. Just start it up and the screen with go partially grey, click and drag to select what you want to capture. The program then closes and opens up a tab in your browser containing said image for your use.

Gyazo is nice because it doesn't involve making an account or having a certain image already saved as a file

Google Drive is nice because it involves no downloads and works with any file, you also don't need to worry about perfectly selecting said image with a screenshot like Gyazo.
