Hosting with Photobucket gives you the added option to select your image size first before sharing your photos on your favorite website. To do this, start by selecting the image(s) you'd like to share then follow the steps below:
Click on the Share button in the toolbar at the top of your screen.
Click on the Embed option.
You will be able to choose the size for your image. The options are Thumb (thumbnail image of your photo), Small, Medium, and Large.
Click on the Copylink button to the right of your chosen image link.
Your photos are shared in their original size if you are copying your image links using Easy Linking Mode.
