I write it on the images - imgflip create the descriptions - and the important thing is, my memes get found by the search engines :-)

Take a look at these 3 random examples - the #'s listed in the description are not from the tags, human or OCR tech has read the small print :-)

imgflip.com/i/3hdx1j
imgflip.com/i/3gjoc7

Type #Cultofcorbyn in to google and select 'images' - then try tell me they don't work lol

Just working through the memes I didn't have chance to post pre election - shame to waste um lol
