На общедоступном веб-сайте у меня есть следующая структура каталогов:
public_html
skipper
includes
functions.php
public
img
DSC_0195.JPG
DSC_0197.JPG
login.php
views
, поэтому внутри общедоступного каталога находится каталог img, а login.php, а внутри каталога img - две jpgs.
Когда я запускаю функцию слияния, расположенную в каталоге include в файле functions.php, я получаю:
Warning: imagecreatefromjpeg(): gd-jpeg: JPEG library reports unrecoverable error: in /home1/sailwbob/public_html/skipper/includes/functions.php on line 707
Warning: imagecreatefromjpeg(): 'img/DSC_0195.JPG' is not a valid JPEG file in /home1/sailwbob/public_html/skipper/includes/functions.php on line 707
Я вызываю функцию из файла login.php, который находится вобщедоступный каталог:
merge('img/DSC_0195.JPG', 'img/DSC_0197.JPG', 'img/merged_test.jpg',0);
и вот функция слияния:
function merge($filename_x, $filename_y, $filename_result, $mergeType = 0) {
// merge('images/h_large.jpg', 'images/v_large.jpg', 'images/merged_har.jpg',0); //merge horizontally
// merge('images/h_large.jpg', 'images/v_large.jpg', 'images/merged.jpg',1); //merge vertically
//$mergeType 0 for horizandal merge 1 for vertical merge
// Get dimensions for specified images
