Hey mate,
when you try to make a full screenshot , what app you're using ?
you may use AwesomeScreenshot addon for chrome/firefox ,
it's simple & easy one & you can crop exactly what you need before saving image on PC.
then add the TI 2018 reviews watermark on the pic normally by Paint program & dun forget to make it Transparent!
then choose to upload the PiC on (https://imgbb.com/) as posted in thread here for BIG files size
