Thanks for the responses on what programs to use to move my pict grayscale files to GIF. It turns out I had the program I needed all along----Gifconverter. The real problem was something that had never sunk into me in the 3 years I have had a Mac. I have always used my SE at work and a year ago I got an SE/30, but I have never had a high res color or monochrome monitor with any mac. I did not realize the little built-in monitor was not able to do gray scale but pure black and white only. Some of the graphics are so well done as to nearly simulate these images that it never occured to me that I could not view them on my SE/30 or SE. Anyway I discovered that the Applescan picts are in 16 grayscales and thus require of course 16 colors be set on the monitor program in the control panel. This of course cannot be done on my SE and not yet on my SE/30 since I cannot afford a card and monitor (still paying for my SE/30, these Macs are too expensive for my budget-but thats another story always well covered here). So what I am wondering, and probably already know the answer to, is there a way of in any programs simulating the quality I see in these 16 grayscale scans I make on the IIci hooked to the scanner on my SE or SE/30. I can use programs that let me dither the image to a viewable form, but still not any where as good as the original gray scale looks on any 16 color Mac system. I assume the resolution the the built-in montior is simply too low for any such program to fool the system into displaying reasonble renditions of the original gray scale, but I can always hope for something til I get enough $$ to ad a color montior to my SE/30. What I am doing with the images I am scanning is to convert them to GIF so a non-mac friend can use them on his system and share with his group of users. I can use some Mac II's at work occasionally to view the file to see what it will look like, but it would be nice to be able to do it at home also where the BBS resides that I am posting the files to for my friend. If you know of a way to trick the SE/30 into displaying reasonably well a 16 grayscale file let me know here or send me email Again thanks for your responses to my earlier question.
