I failed to come up with a quick example for the new third parameter of _LOADIMAGE(), didn't pay attention that the string is supposed to be just like one that could be loaded from JPEG, PNG, PCX etc. graphics file format. Enjoy this, it's my first successful experiment ever with _MEMCOPY. A good improvement is to change the palette, either as greyscale or along a cool gradient.

#286 - Added support for opening image from memory using _LOADIMAGE() - @a740g, @mkilgore
_LOADIMAGE() has a new optional requirements$ argument, similar to the string argument to _SNDOPEN():
_LOADIMAGE(fileName$[, [mode&][, requirements$]])
Providing "memory" in the requirements will cause _LOADIMAGE() to treat the contents of the fileName$ argument as an image file itself, rather than attempting to open a file.
Bug Fixes

Note, this source code runs in QB64 2.02 and older. Phoenix version comming soon.
What is scratching? It's an effect where the DJ slows down or speeds up the turntable while the sound is playing.
This program tries to simulate this at random times during playback.
Before run it, please write correct music file name in source code to line 13.

NOTE! This program is created to QB64 2.02 (and older, Phoenix version comming soon!)
Compile this program in its own folder (maybe call it echo test, it doesn't matter) and then copy some music files into that folder. The program is built on an older version of QB64, so it only supports MP3, OGG and WAV formats (you can add the other formats there on line 36 in the source code, but it is not tested with it. The program will play music files in the folder with an echo effect after running. The attached direntry.h file is needed for the function.

Hello. I went through the forum and found some questions about saving sound and also questions about whether it is possible to create and save sound in QB64. The answer to both is yes. The attached program is from January 5, 2021, when I was actively involved. Then the forum was destroyed and I vowed not to spend time on something that would just disappear overnight. I'm here today after a long time (I'm using QB64 2.02) and I see that there might be interest in this, so I'm posting it here. My SaveSound16S will be useful, it saves your sound in stereo WAV file format and I used it for testing because SNDRAW had problems with stereo (I don't know how it is with this command now).
This program open your music file, then create WAV file from it named as TestEff3.wav (contains stereo switching) and then play it using SNDPLAYFILE statement.

So it wouldn't take more code lines to do deeper levels. With recursion you could just keep going deeper as long as the side length of a checker was >=1 pixel.
An old routine which I found on my drive, which showcases how to embed text into an image and hide it from most folks prying eyes.
EmbedText.7z (Size: 1.1 MB / Downloads: 80)
<-- Grab the archive here, extract, and run with "OUTPUT EXE TO SOURCE FOLDER" enabled in the run menu.
What this does, breaks down to these steps:
1) It loads an image for us.
2) It then embeds text into the image, without disturbing the image in any way noticeable to you. It'll display it on the screen for you to stare at in awe at the sheer lack of text upon it.
3) It then decrypts that text back off from that image and puts it onto a blank canvas, to display for you to stare at in awe, just so you can see that the process here actually works.
Hidden text in images!
I use this all the time for photos and such, to embed names, dates, places, occasions, and whatnot into the image itself, so I can just draw that info out anytime I ever want in the future -- and it still won't be visible for the general public to ever notice.
I have a folder containing several images (.jpg) that I want to place in an array, then pick any (or all) from that array to display. I don't see any appropriate commands that allow this; are there any? (simplicity is important to me!)
