This topic does cause some confusion, so I hope the following will help.
Image resolution explained: Photography resolution is a measurement of image quality, so you may define resolution by how much detail is in your print. If your print has sharp detail you may consider your image to be of good resolution. If detail is blur in your image you may consider your image to have poor resolution. Good resolution is a direct result of having a large number of pixels in an image.
Pixels explained: Digital images are made up of millions of small dots - each dot is called a pixel. Each dot contains a small piece of image information, and when added together with the other pixels you'll get your final image.
Print resolution is measured in pixel per inch (ppi) or in dots per inch (dpi) - both hold the same value. 300ppi means that there are 300 pixels per inch or 90,000 pixels per a square inch.
What size can I print my images?
A digital image that's 1500ppi wide will print a 15-inch wide print if the print resolution is 100ppi. If you change the same image to a print resolution to 300ppi your final print size will become a 5-inch wide print.
If your image file is 3000ppi wide x 2400ppi high with a print resolution 300ppi, your final print size will be 10 x 8 inch. The same file with a print resolution of 150ppi will give you a final print of 20 x 16 inch.
Divide the print resolution into the pixel width or height of your image.
Higher resolution should not be taken to mean that your images would be of higher quality - your images would only be of high quality if you print to the correct format. Example - if you print a 3000ppi x 2400ppi size file to a print size of 20 x 16 inch at 300ppi, the pixels may be visible resulting in a blur image. You need to print it at 600ppi to attain good quality.
What size resolution should I use?
At 600ppi (which is an extremely large resolution) your image will be supreme sharp. You will be restricted with print size.
Printing your images at 300ppi is the standard quality. Image sharpness doesn't get much better. The only setback is that the maximum print size will be restricted - you might need to drop the resolution to get a larger image.
If you need a large print from a small file print your file at 150ppi - your print will lack detail and the pixels may be visible. You should not print an image any smaller than 150ppi.
72ppi is standard with your computer screen. Don't print your images at this size - the pixels will be visible.
Resolution tips: Scan your images as large as possible; it's easy to resize them later. If you scan an image to small you may have to re-scan at a later date to get a larger print.
If you need a print that's twice the size of the original - scan it at 600ppi and print it at 300ppi.
Try to print your image at 300ppi.
If you use a tripod when taking an image you may be able to push the print resolution lower than the recommended 300ppi - this will enable you to get a larger print.
Other Tips: Be very careful when cropping an image, if you crop it too much you will reduce the print size.
Be careful not to confuse print resolution with printer resolution; printer resolution is measured in dots per inch (dpi), but these values are a great deal higher- common printer resolutions are 2400dpi and 5760dpi - this is a measure of the amount of ink dropped onto your paper per inch.
We all know that there are thousands of web-sites and books peddling all kinds of methods for self-improvement and personal growth. We know because we've read perhaps not most of them but at least one typical specimen of each category, a (re)search quest that started over fourty years ago.
But let's get back to the basics: what does (physiologically) constitute intelligence?
There's but one thing that sets a more intelligent brain apart from one a little less so, its internal "wiring":
1. the amount of connections (synapses) that relate brain cells with each other and equally important
2. the strength of these pathways
3. and how they relate with each other.
The way brain cells can interact with each other is virtually unlimited, that is to say, trying to calculate all possible combinations leaves us with a figure that's many times higher than even the amount of atoms in the whole universe.
Then there's also the speed with which new connections are formed, but research seems to suggest, that both human "subspecies", those who are forming new connections rather quickly and the "neurologically slow" both have their mutually exclusive advantages in survival which is why both sets of genes are still transmitted down through the generations. We'll discuss this topic in a forthcoming article.
Now, if the three points shown above by and large constitute the physiological basis for intelligence as it seems to be measured by standard tests, then we must only find out how these connections between cells (neurons) are increased? Well, as everyone knows, this process is simply called learning. The interesting thing is though, that learning can as much happen by interacting physically (including smelling, listening and seeing!) with your environment as well as interacting with a virtual world, like in thinking, meditation, contemplation etc.
This virtual world is for your brain cells every bit as real as the outside world, and the reason is easy to understand: that "outside" world does not exist for your brain - it is transmitted to your nerve cells via electrical impulses and it makes no real difference where these impulses are generated.
So when you vividly remember something you are training those pathways as much as if you experienced the scene physically that is now a memory! You can only exercise a limited amount physically per day without completely exhausting yourself but you can relive as many memories as you wish per day and you can create new experiences in your brain by ... well, being creative! Since your subconscious mind does handle about ten million times more data over time than your conscious mind does, the most powerful method of creating an extra load of traffic on your neural pathways is to let your subconscious take over. That pretty much describes what image streaming is all about: associate freely and let flow and come forth everything that your subconscious produces. Since most of your memories are visual images, even if you are not consciously aware of it, this requires to let images flow freely, or, in other words, image streaming. And if you practice steadily and repeatedly you will eventually increase your IQ considerably as you beat new paths and create new paths (associations) between hitherto less or unconnected areas of your knowledge. And that, in essence, is intelligence.
Here are some resources that prove the point or shed more light on the subject:

It doesn't matter, if it's really 20 IQ points or less, the main point is: no matter where you start from, if you practice only a few times you will notice a much richer stream of visul imagery that helps you find creative solutions and helps to keep your brain fit - which is even a good way to stave off dementia, Alzheimer's disease etc.
