Loops button jpg text

Hi

I am very new to all this and want to learn but am struggling to get the thing explained so that I understand

Do you know of a good simple tutorial that explains how I can use loops to load jpgs and text sometimes from a single button and sometimes from multiple buttons.

If any body could show me some code snippetts with an explanation it would be good.

To press one button and load one jpg and text is ok but to get one button that each time it is pressed loads the next picture with its text fromexternal files is something else and when I then need several buttons that each load a different jpg with its text wow.
