here I would like to create an auto generated number that when I chose the image of the browse button, then the image will appear in the axes, along with that then an auto number will automatically appear in an edit text. For example for the first time, then the ID to be shown is 001, then I'll save that data to the MySQL database. Furthermore, when I choose a new image, which will show the ID is 002, That is so, how so I can make it that way?

i think we got miss comunication here. I have a GUI like this :

I want to make automatic number every time I select a photo from the browse button, where each number that will continue to sequence. For example for the first data I stored to MySQL database, has ID 1, for the second data I stored to then have a MySQL database ID 2, and so on, each number will be increased so that no duplicate numbers.

@Alvindra Pratama: then you will need to initialize and store a counter scalar, and increment it by one each time you generate a new ID. Possibly the best place to store the counter would be via guidata.
