Dear thuyltt
I put image in "public_html/templates/sj_news_ii/images/placeholder"
also "public_html/images/placehold"
and test 2 path in "placehold.php"
/templates/sj_news_ii/images/placeholder
/images/placehold
But the picture was not seen

Thanks for your guidance

Dear shahrouz,
This code:
return '<img src="../images/placehold/'.$size.'" alt = "'. $alt .'" title = "'. $title .'"/>';
../images/placehold/'.$size.'
Please change to:
../images/placehold/your_image.png(or jpg)

Thanks.

Dear thuyltt
This is wrong " ../images/placehold/your_image.png(or jpg)"
In file "placehold.php"
'<img src="/images/placehold/'.$size.'" alt = "'. $alt .'" title = "'. $title .'"/>' Must be true
And must be loaded different sizes
But I do not know why the images are not loaded

Thanks.

Dear shahrouz,
When you use images from website: placehold.it/ It can choose size, but now you use image from your site, it need a image name to load and display, they are different.

Thanks.

Dear thuyltt
I've used this code on another site ('<img src="/images/placehold/'.$size.'" alt = "'. $alt .'" title = "'. $title .'"/>')
and Resized it done
But does not work this site

Thanks.

Dear shahrouz,
Please change /images/placehold/'.$size. by /images/placehold/image-file

Thanks.
