Suppose I have a .jpg or .png or whatever, and I want to display it on a color Apple II monitor. Is there a procedure for this? If not, then what about converting the image into 40-column ASCII text?

You have two options. You can get a converter cable from your modern computer to output to a composite signal, and run the signal directly to the color composite monitor (which is what most Apple II monitors were). Unless you're talking about the rare RGB monitors (or a IIGS monitor). Your other option is to convert your still image to a GIF format. There was a program on Apple II's that can display a GIF picture file. I think that is on the common archives (like Asimov).
This program works very well.

Thanks for that program! Works fine!
But how can I open the hgr, dhgr data on an Apple II?
The easiest way is to use a disk emulator with a flash card. Rich Dreher makes the CFFA, if you haven't already got one.

Alternatively, use a superserial card and ADTpro.

or do I misunderstand the question?
Thanks... I do have both...
I mean how to show the picture on the Apple II?
BLOAD does Not work ...
A couple of things.
1. The program creates 2 files - a png and the binary. Use the binary, of course.
2. In ciderpress, once you've moved the file over, you need to change the attributes aux type to $0800. I'm not sure why to be honest. I'm sure you could figure it out by digging through the DOS documentation.
Then it should bload fine.
(ducking and running in case that wasn't funny....)
You can use Buckshot for the converting. it can directly generate a disk-image for use with the cffa3000.
If you want more options, you can use Bill Buckels command line tool BMP2DHR (on which Bucksot is based on).

I don't have a '3000 but I do have a ADTpro and CiderPress both working.
I tried Buckshot. It took my round image and made it horizontally oval.
Hi,
@tohgr
First "HGR" then BLOAD ... all is working fine!
What also works is: putting my image into the slide show disk image from the webside ... then it is shown!
@buckshot
Creating a 800k disk image is possible ... a 140k not?
There was a program that showed GIF files on my iie.
It was called, "][GIF" or "IIGIF".
The Apple II doesn't have "square pixels" like a modern computer. If you want a converted picture to be perfectly proportioned you'll probably need to figure out what the exact display ratio of your monitor is so you can pre-scale the pictures you want to convert to compensate for it.
(IE, you could try converting a graphic that's just a square, say, 150 pixels on a side and, of course, looks square on your modern computer. Displaying the converted picture on your Apple II, measure the sides of the square, and use the resulting measurements to compute a ratio to use as a fudge factor for prescaling the input, which you can do in any graphics program that allows non-proportional scaling of pictures.)
