The window will be placed in the middle of the screen by calculating the position by using the screen properties. The function accepts the image filename, the size of the image, and the title of the image as arguments. Next, the height is increased. Then, the starting position for the new window is calculated based on the size of the screen and the size of the image window. The function then opens the new window. */ function ViewImage(ifile,ix,iy,ititle,idesc) { ix = eval(ix + 8); // Calculates how many lines the idesc will need and adds that to the height of the window. iy = eval((Math.ceil(idesc.length/(ix/8.06))*20) + 60 + iy); // Centers the window starting coordinates in the center of the screen. var ixstart = Math.round((screen.availWidth - ix) / 2); var iystart = Math.round((screen.availHeight - iy) / 2); if (ixstart < 0){ ixstart = 0; } if (iystart < 0){ iystart = 0; } var win = window.open("","imageviewer","status,width=" + ix + ",height=" + iy + ",left=" + ixstart + ",top=" + iystart + ",scrolling=no,resizable=no,menubar=no,toolbar=no"); win.document.open(); win.document.writeln(""); win.document.writeln(" " + ititle + "<\/TITLE>"); win.document.writeln("<\/HEAD>"); win.document.writeln("<BODY BGCOLOR='#FFFFFF' topmargin='0' leftmargin='0' marginwidth='0' marginheight='0'>"); win.document.writeln("<CENTER>"); win.document.writeln(" <IMG SRC='" + ifile + "' BORDER='2' ALT='" + ititle + "'><BR>"); win.document.writeln(" <TABLE BORDER='0' WIDTH='90%' CELLPADDING='0' CELLSPACING='0'>"); win.document.writeln(" <TR><TD ALIGN='CENTER'>"); win.document.writeln(" " + idesc); win.document.writeln(" <\/TD><\/TR><\/TABLE><BR>"); win.document.writeln(" <A HREF='' ONCLICK='top.close();return false;'>"); win.document.writeln(" <IMG SRC='images\/close.gif' BORDER='0' ALT='Close Window'><\/A>"); win.document.writeln("<\/CENTER>"); win.document.writeln("<\/BODY><\/HTML>"); win.document.close(); }
