did you adjust the img/index.php for the usage of the crc32 function ( example is in the img/index.php )

Thanks, that was the issue. The same define as in the xhelpers.php should be enabled in the index.php
Code:
define ('DF_IMAGE','concat("https://www.website.nl/img/",`feed_id`,"/",crc32(image),"-",`items_id`,".jpg")');

Is it also possible to create different sizes (using percentages) for the thumbs based on the original height and width? The publishers never use the same imagesize. In the index you'll have to specify a height and width, but in pixels the proportions are not right for every image when displayed.

The 404 script should resize with the correct aspect ratio, adding white space to get the right size.

This could get ugly on a website with a coloured background, although a lot of images have white background already.

the 404 script could be changed to resize only, best fit, without adding white-space.

or the background color for the padding can be changed
Code:
#no padding 1 $dst_img=ImageCreateTrueColor($new_x,$new_y); imagealphablending($dst_img, true); # black is white $white = imagecolorallocate($dst_img, 0, 0, 0); imagefill($dst_img,0,0,$white); #no padding 2 imagecopyresampled($dst_img,$src_img,0,0,0,0,$new_x,$new_y,$old_w,$old_h);



the 404 script has been updated including these examples, and a fix for image urls with encoded '&'

I still can get it perfect. Some images show the "no-image", but i see the image is in the folder. The script is looking for this url: www.example.com/img/56/255996879-132466.jpg but cant find it.

When i enter the url, in the browser, without 255996879- it shows the image correct.

Whats happening here?

The pevios version of the script missed a vital part to compile the directory correctly.

the zip is updated
