Testing on custom pictures

[DecentMakeover]

Hi I have replaced the images in the imgs folder with some of my custom images,

after which i run compile.sh picture which runs successfully,

but when i execute run.sh picture i get

`OpenCV Error: Assertion failed (ssize.area() > 0) in resize, file /build/opencv-ys8xiq/opencv-2.4.9.1+dfsg/modules/imgproc/src/imgwarp.cpp, line 1834 terminate called after throwing an instance of 'cv::Exception' what(): /build/opencv-ys8xiq/opencv-2.4.9.1+dfsg/modules/imgproc/src/imgwarp.cpp:1834: error: (-215) ssize.area() > 0 in function resize

Aborted (core dumped)`

Do i have to resize my images into a specified format ?

Any ideas would be helpful.Thanks in advance
