schon seit langem bin ich auf der Suche nach einem vernünftigen Image-Resizer, der vor allen Dingen Thumbnails erzeugt und nicht nur via JavaScript-Verkleinerung on the fly arbeitet. Bilder können meine User mit UploadPic hochladen. Dieses sollte ja laut dem Autor um eine Thumbnail-Funktion erweitert werden (dann wär's absolut perfekt), doch mit der Einführung von phpBB 3 wird in dieser Richtung m.E. nichts mehr geschehen. So stieß ich auf iMinimize, der im großen und ganzen das macht, was ich will. Doch ich habe mich zu früh gefreut:
Da einige User verschiedene Bilderupload-Seiten (PostImage/ImageShack etc.) verwenden, werden oft Thumbnails mit [ img ]http://...[ /img ] verlinkt. Leider überschreibt iMinimize dies und es ist nicht möglich, das Bild in voller Größe zu sehen.
Wahrscheinlich müßte man etwas irgendwo in den BB-Code-Dateien ändern, aber dazu reichen meine Kenntnisse leider nicht aus. Vielleicht weiß hier jemand eine Lösung, dafür wäre ich echt sehr dankbar. Ich hätte nie gedacht, daß es so schwierig ist einen Bildresizer mit Thumbnail-Generierung zu finden.
Hier ist der Code von iMinimize:
