Why can't everyone upload it? It always shows that the upload failed.

There are two reasons why small websites fail to upload pictures.

First, your picture is too big.

Second, your picture format is wrong. Generally, the picture format is changed to *. JPG will do.

Change the picture to *. JPG, let me teach you. Open Start-Programs-Accessories-Drawing, and open your picture in it.

Then click Save As and put a * in the drop-down box before saving. Just change BMP to JPG.
