Hallo,
ich möchte gerne zusätzliche Thumbnails erstellen lassen, um diese Definierte Größe in Beiträge einzubinden.
Das einbinden an sich klappt auch schon, mit dem dateinamen: phoca_thumb_f_'variable'.jpg wenn ich die datein manuell erstelle und in den Thumbs ordner hochlade.
Ich finde allerdings keine Datei wo die Thums generiert werden, ansonsten bräuchte ich dort ja nur den Code für phoca_thumb_l_'variable'.jpg kopieren & ändern.
Würde mich freuen wenn mir jemand helfen oder Tipps geben könnte.
Grüße Rouven

Hi,
I want to make create additional thumbnails to include this size in Defined contributions.
The embed itself works already, with the filenames: phoca_thumb_f_'variable '. Jpg when I create the files manually and in the Thumbs folder upload.
However, I find no file where the Thums be generated, otherwise I would need to change there, so only the code for phoca_thumb_l_'variable '. Jpg copy &.
I want to create a fourth size.
Would be glad if could someone help me or give tips.
Greetings Rouven

Re: Create additional Thumbnail
Hi, this needs to be customized in the code, you should see libraries folder in administration, you can find there classes for image and imagemagic (these are producing the thumbnails)

Re: Create additional Thumbnail
You need to see which methods are calling imagemagic method and these methods declare which thumbnails should be done, so you need to add information to these methods, so they will call the imagemagic e.g. 4x
