upload and rezize multiple images |
Descriere:
sunt 4 fisere care fac upload la poze si apoi rezize in tr-un dosar `thumv`. primul fiser stabileste numarul de poze care sa se upload-eze... al doilea e form-ul de upload, in functie de primul fisier, al treilea fisier face upload-ul iar al patrulea face resize... sper sa poata fi adaptat. Am realizat acest script in urma discutiilor de pe forum-ul www.phpromania.net/forum. Codul trebuie optimizat pt anumite tipuri de imagini! | | Trimis de:Octav Octavian | | Voturi:112 | | Accesari:824 |
