FRAPS is outdated and unmaintained and shouldn't be used anymore. The best option is to use the bundled software that come with your GPU drivers either from Nvidia or AMD depending on your card. Either this or the feature to record thats built into windows 10.
No need to use 3rd party apps anymore anyway.
Also imgur is a bad choice, https://imgbb.com/, https://imageshack.com/, https://imgshare.io/ are all much better.
