I make a simple story out the Images, and play it back during recall.
Memory palace with 2-3 images per loci.
I use Number-Rhyming and associate each image with its relevant number. Probably not the best if you’re after speed (my fastest to date is only about 53 seconds), but I find it the easiest method for me.
Some asked me this today, here my answer:
Using the method of loci and a memory peg list for numbers from 00-99 or a 0-9:
*Each target “image” (picture) you will link by anything that comes to mind with an “peg image”, let’s call this combined image: mnemonic image. Some champions do this, like Yanjaa.
*Each mnemonic image you’re going to place it within a memory palace.
You create a mnemonic image for each picture and place it within a locus of a memory palace as soon as possible.
Visualize each picture with a cue that will remind you of its numeric position. The cue could me peg image from a number list but other kind of cues are useful too. I have even tried picturing the numeric symbols in tandem with the images and I was able to recall many but not very fast.
