<div>Harusnya $count di taruh di luar if yg pertama aja, biar pas di panggil di if yg bawah masih bisa,<br>Sebelum :</div><pre><!doctype html> <html> <head> <title>esp32-cam photo gallery</title> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <style> .flex-container { display: flex; flex-wrap: wrap; } .flex-container > div { text-align: center; margin: 10px; } </style> </head><body> <h2>esp32-cam photo gallery</h2> <?php // image extensions $image_extensions = array("png","jpg","jpeg","gif");
