I need a little computer geek help...

[Archae]

I have four picture files, that end in the suffix, ".ilbm256"

Is there a viewer or better yet a converter that will let me see them in Windows 8.1?

1. not .jpg or .jpeg or .png or .gif etc ?

Never heard of that file extension and google comes up blank so far, admit I did not look for a long time.

2. Make a copy of the file and rename it to .jpg suffix and see if it opens.

If it does, do it to all of them. If it doesn't, then they may be in some proprietary format.

8. Sorry, it doesn't work.

I'm almost positive these are Amiga files.

9. Some questions and thoughts

Are you Windows or mac based?

Most extensions are three letters, not 7. Your actual 3 letter extension may be hidden, and you are seeing part of a file name, not the extension.

Just guessing this is a file that belongs to some program that created it. The name seems to suggest:
'i' (don't know what that is for, but maybe ' info' ?)
'lbm' (library manager?)
'256' (perhaps encoding e.g. not 128 bits, but 256 bits)

Investigate what programs you have that manipulates images and where it originated to see if you can find parent program that created files.

Some programs stamp their files at the top with name of program and version. You can force Word to open any file. Usually you will see garbage, but often the text stamping of the program will be at the top or bottom of the file and be readable

You can also try to get some other program to force open the file if you can get it to disregard the extension. DOn't know of any of these off hand. Maybe others can suggest something....

10. InterLeaved BitMap. That is an old Amiga format

Variant of IFF

You might be able to rename them with an iff suffix and use an iff converter
