Here's another private message to Adywan I would like to hear your guy's input on:

About image files, I took a screen image snapshot (using the PrtScnSysRq key) and tested different file formats on it to see the sizes different formats save it into. I found the 24-bit Bitmap (5.93MB) is the file format that saves the images in the largest file size by far which I am assuming is the highest quality? I noticed 256 color Bitmap (1.97MB) saves the image in the second largest file size, followed very closely by TIF (1.93MB), which is the format of the images above. But they are smaller when saving from a 24-bit Bitmap image to a TIF image (793KB). But 256 color Bitmap looks much worse quality than TIF? Fourth is PNG format (1.23MB). 16 color Bitmap is the fifth largest size (930KB) and then GIF (265KB), JPEG (264KB), Monochrome (253KB), all pretty much save in the same size. I used the exact same image to compare all of these file formats saving the screen snapshot separately every time and not saved over the previous file format. Does this sound right to you? What are these different file formats used for? I know GIF can be used to make low res moving images in clips like 24 frames long. How do you make those? I am assuming you capture a short video clip and then convert it to GIF format? Can you do that with any other file format? What is the PNG file format? I rarely see that format used. JPEG is by far the most popular, but I don't like it because it compresses the image and continues every time you re-save it. I like 24-bit Bitmap because I assume it compresses the least or maybe none at all? But 24-bit Bitmap, TIF, PNG, and JPEG all pretty much look the same I think.
