Predmet:Prikaz slucajno odabrane slike

Zelim odabrati sve slike iz foldera i staviti ih u array,
zatim bi slucajno odabrao sliku iz array i prikazao na web stranici.

1. odaberem sliku i stavim u tablicu-ovo radi
PreuzmiIzvorni kôd (HTML):
  3. <title>slika u tablu</title>
  4. </head>
  6. <table id="mainTable" width="578" height="351" border="1">
  7.   <tr>
  8.     <td><img src="majstor.png" alt="" border=3 height=100 width=100></img></td>
  9.     <td>Some content</td>
  10.     <td>Some content</td>
  11.   </tr>
  12.   <tr>
