Images are not showing when page load

Hello All

I am having lot of webparts on my page.

In two of them webpart i applied xslt and showing image of created by person in this

1)Announcement webpart(Wall updates)

2)Showing blog using content by query webpart(Blogs)

While page loading not able to load images in both webpart view.

But when i decreases webparts on page images rendered properly.

I think it is taking time to fetch webpart so timeout and showing default images.

Kindly suggest me some way to tackle and images will dispalyed properly

Thanks in advance
