Non trovo nessun errore su quella riga.

[Riky77]

infatti è strano !! non capisco cosa possa essere successo quando apro un forum e clicco nuovo argomento mi si presenta questo errore

[Carlo]

Visto che a parte questa MOD, il tuo profilo dice che non hai MOD installate, ripristina questo file prendolo da un pacchetto pulito e rieffettua le modifiche.

[maverix]

Non si sa più nulla di questa MOD??
Il sito di Xiradon risulta ancora OFFLINE, qualcuno ha consigli?
Nel PCA ci sono vari parametri da cui impostare i px massimi delle immagini ma non capisco come funzionano, ho provato ma senza successo.
Ho visto un forum che le immagini hostate e che poi si inseriscono nel tag IMG anche se gigantesche si riducono in automatico e si vedono per intero, poi diventano anche link per l'ingrandimento.
Domanda: è una MOD o sono solo i parametri del PCA impostati correttamente?
I parametri da PCA servono SOLO per gli allegati o anche per immagini inserite nel tag IMG????
Grazie a chi risponde.

^^ Si e' la Prettyphoto Attachment

Grazie, ho visto sul .com, ho visto l'anteprima, non è esattamente come nel forum che ho visto io.
Li le foto vengono ridimensionate ok, ma il link porta ad una nuova scheda del browser dove poi l'immagine si vede a grandezza naturale.
Questa del com invece mi pare di aver capito (se è esatta la demo) che carica anche dei plug-in per farla vedere anche come sequenza automazizzata nel caso ci siano più immagini, non so se mi sono spiegato.
Rimane il fatto che vedendo il tread ho visto troppe ulteriori modifiche, e siccome io di inglese capisco ben poco preferisco non avventurarmi in un'impresa troppo grande per me.
Quella che linkate a Xiradon potrebbe essere quella giusta, ma come dicevo sopra è ancora offline pur dicendo che avrebbe ripreso a fine settembre
Nessuno di questo gruppo è in grado di fare una MOD come ho descritto quella vista in un altro forum?

[maverix]

Spulciando il sorgente del forum dove so che funziona il resize image ho visto questo codice, vi dice qualcosa?

Codice: Seleziona tutto

<script>
     onload_functions.push('resizeimg();');
    function resizeimg()
    {
       if (document.getElementsByTagName)
       {
          for (i=0; i<document.getElementsByTagName('img').length; i++)
          {
             im = document.getElementsByTagName('img')[i];
             if (im.width > 600)
             {
                im.style.width = '600px';
                eval("pop" + String(i) + " = new Function(\"pop = window.open('" + im.src + "','phpbbegypt ','fullscale','width=400,height=400,scrollbars=1,resizable=1'); pop.focus();\")");
                eval("im.onclick = pop" + String(i) + ";");
                if (document.all) im.style.cursor = 'hand';
                if (!document.all) im.style.cursor = 'pointer';
                im.title = 'Clicca per ingrandire l\'immagine ';
             }
          }
       }
    }

    </script>

[Micogian]

Si, è javascript. Dovrebbe funzionare.
Va messo in overall_header, prima del tag </head>

[maverix]

Appena provato, non funziona.
Comunque nel sorgente della home page non c'è.
bisogna simulare un argomento con dentro una immagine, allora si vede tale code....
