Hello,
I am creating a report that uses the employee_id to get the Image from the server.
What I have done so far is :

I created a new report with the simple select statement as :

select 
'\\172.15.10.25\departments\Interfaces\employee_Images\'||
employee_id ||'.jpg' Image 
from
employees ;

Then I set the field to be :
Character.
Read from File : Yes.
File Format : Image.

I always get this error :

REP-0606: Unable to read link file \\***********.jpg  Check link file format

I have read that oracle developer 6i supports reading files such as jpg, bmp , etc.
My problem seems that the developer can't read the file, but the question is why ?
Do I have to modify anything ?
Any clue ?

It can certainly read files from the file system it's running on.
But you appear to be trying to read the file from somewhere else.
I'm not sure it supports paths like that.

I will try to use a local directory and check if it works.

I have tried to set the folder in D: and modified the directory. The same problem occurred.

Have you specified the path correctly?
Is the folder on the reports server?

I have rechecked it. The path works fine.

how large are the files?
A quick google suggests reports can't cope with anything large

Yeah, Right.
I minimize the size of some pictures. The images which are greater than 2 MB couldn't be displayed. Small sizes pictures were displayed. A question came on to my mind. What is the maximum size of the image to be displayed in such a report?

From my own experience, it is not about one image size, but total size.

For example, I had to display manager's signature at the bottom of each page in the report which produced e.g. 1000 pages. It failed. But, when I reduced scanned signature's image size from 100 KB to 5 KB, everything was OK.

So ... it just depends.
