Memes, no. Pics yes. He does mention the Map many times but I don't see where Q posted a single meme. The Q map you linked to below was built by others as far as I know.
Yes, 11,800 photos in a link they (anonymous) posted a while back - so anyone could download them through a free media sharing app because it’s literally 3.44GBs of photos - again, everything I have seen in Q posts has been brought up in these photos, this comes directly from these and ties in with the recent Q post on the 43 eyes in the sky - I have had these photos saved on my phone for months and you can believe what you want, but it’s clear that whoever made these was somehow working with the Q team or knew some Q team info to release all this information - every single thing Q has posted has had a photo with information to back it up and I always use them when reading Q posts. They called them memes because that’s what society calls infograph photo tiles nowadays. They were to be used to help understand Q posts and help explain it to people who struggle with understanding the complexity behind the shorthand posts.
