How to drive a 3” TFT
It would probably be a big challenge to get that display working with an Arduino, for a few reasons.


It has an 40-pin flat flex connector. You'll need a suitable socket to plug it into, which breaks out the signals to something breadboard-friendly.
How will you interface with it? It says it has an 8/9/16/18 bit interface, but does it have data sheet explaining how? It's probably using a standard interface, but which one?
Where will the images come from? The flash memory on an Arduino Uno is only 32KB, which wouldn't be enough for even one image.


A better approach would be to find something friendlier at SparkFun or Adafruit, like "2.8" TFT Touch Shield for Arduino with Resistive Touch Screen", at https://www.adafruit.com/product/1651.  Note the "for Arduino". It's a shield that plugs directly into an Uno. As a bonus, it has an SD card slot as well, which can hold your images.  It should also come with documentation and some sample code, which is a huge help.

I'll bet one of the sample programs will display .BMP images from the SD card on the LCD.  Dealing with JPEG files requires decoding them first before you can transfer the pixels to the display, so stick with BMP, which will be much simpler.

And the price is only double the Ali Express item, which is cheap for something with the above features. But you need 10 of them, so you'll have to decide if it fits your budget.
