Stamp Image File Identification

Hi

This is to find out if anyone would use a WINDOWS program to add information to an existing Stamp Image file. I am finishing up a little project now and this would be next.

I already have a simplified version for myself and was wondering if it was worthwhile to upgrade the software to make it more universal.
The program is for WINDOWS only and it places the following identification into a stamp image file. The image file format, however, must be a .JPG or .JPEG as it is the only image file that can accept this info. Once this info is added then placing the mouse over the image file, mouse hover, would display the info.

Added Information:

Data           Description                   Limits or Format
Country        The stamp Country             30 characters
Title          What the stamp represents     30 characters
               ie; Latin name of a flower  
Issue Date     The issue date in the format  MMMMMMMMM DD YYYY
               of Month Day Year        
Subject        A possible Topical subject,   30 characters 
               i;e Flowers
Catalog Name   The name of the catalog used, 24 characters  
               ie; Scott or Stanley Gibbons
Catalog Number The catalog number            12 characters      
Perforation    The stamp perforation,        vv.vv x hh.hh 
               i.e; 12.5 x 14 or 12.5
Size           The stamp size as             n,nnn.nn x n,nnn.nn 
               Width x Height

The limits are governed by the maximum data allowed for a file field.

The only data that is identified by 'name' is:
C: Catalog Name
N: Catalog Number
P: Perforation
S: Size

All text files will allow foreign characters inserted by a customized character map. There would be edit features for adding Catalog Names, Catalog Number prefixes and Subjects. I would also add some sort of search feature.
