<span style="font-size:12px; line-height:15px Hi,

I am using the following<span style="font-size:12px; line-height:15px code, and it works for binary image download, but the problem is:
<span style="font-size:12px; line-height:15px <br/>
For an image file with 18k size on server side, only 4k can be download and just half of the image can be seen on the client side. <br/>
<br/>
Any ideas?<br/>
<br/>
Thanks.
