Hi guys

I have extended the image class so that I can use custom GD resizing but it seems to have broken my files & images section in the CMS which brings up the following error:

Fatal error: Class 'DailyImage' not found in C:\wamp\www\silverstripeSDE\sapphire\filesystem\Folder.php on line 107

The code which extends image is in Page.php and reads:

class DailyImage extends Image {
function generateThumbnailImage($gd) {
return $gd->croppedResize(178,105);

I had a look in Folder.php but cant figure out whats going on :S
any ideas?

Thanks in advance

Have you done a DB build?. You might also need to make sure that class is in a seperate file eg DailyImage.php so SS can pick up that class

perfect thanks Willr, it needed to go into its own file.

I will correct the tutorial in the docs that said to put it in Page.php

thanks for your help :)

EDIT: hmmm how would I go about editing the docs for this? Am I wrong in thinking its like the wiki where anyone can edit? I can't seem to edit with my forum I need a special login?

OK I know why this was going wrong, if you want to include the image extention class inside Page.php then it needs to be in the form PageName_Classname so in my example it would need to be called 'Page_DailyImage'. Otherwise it needs to go into its own file.

I have added another line to the description on this page to make this clear: [url][/url]

thanks for your help willr!
