>Well, first, you have to decise on how to store the references to the pictures. Maybe just a character field with the pointers to the pictures. Since there can be more than one picture, I would use some character to delimit the pointers. Then when you want to show the list of pictures (building a listbox), you can use the AT() and SUBSTR() functions to build the list as you would like. I would do something like this when storing the list of files:

****** this stuff was cut out because I used the tab-type of brackets in error

(filename1)(delimiterA)(description1)(delimiterB)(filename2()delimiterA)(description2)...

>>WITHOUT storing image in the database or table (as Object or General, whatever), how to link the Decal to DOS file (*.jpg) as well how to display the picture by a click of a button (on a form)? Displaying one picture would be easy, but if there is multiple picture for one Decal record?
>>
>>Example (just an example!): One record, Decal is "PC2233" and there are 4 pictures for "PC2233", via, CPU, monitor, keyboard, and mouse. How would I display the pictures as well how to have a pop up list or something since there are more than 1 picture for the user to pick to display rather showing four new windows of picture of each item?
