However, if I want to show many images on one page, such as a table like this: user_id_1 user_name_1 user_portrait_1(image) user_id_2 user_name_2 user_portrait_2(image) user_id_3 user_name_3 user_portrait_3(image) user_id_4 user_name_4 user_portrait_4(image) user_id_5 user_name_5 user_portrait_5(image) Is there a way to do it? I used to use display tag to solve similar table display, but with image URL, it doesn't work. -- View this message in context: http://www.nabble.com/Struts-2-File-upload-to-store-the-filedata-tp14168069p23970105.html Sent from the Struts - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
