Hi Alison,

I suspect the problem is caused by the method you are using to read the
file. IMAGEMAP doesn't know anything about data files: it just plots
arrays that already exist in memory.

Can you be a bit more specific about the type of data file you are
trying to read? For example,

How many pixels are in each row?
How many rows?
What is the data type for each pixel (e.g., byte, 16-bit integer, 32-bit
float)?
How many bytes of header information (if any)?

Cheers,
Liam.
