You go to tinypic.com and there you upload the image you want to share, you put the file type as an image, then you can resize it to the size that you want. After you are satisfied with your options you click in upload now and you will need to answer a capcha to see if you are not a robot, after that you will get 4 texts, copy the one that says "IMG Code for Forums & Message Boards", and paste it on the post you will like to share it and tara! You are done!
