Hello again!

I was just looking over a set of photos I took a while ago, only to find that loads of them have been ruined by some horrible black specs all over the image. Since then I have taken a few more sets and cannot see any marks on these photos at all! I have attached a link to an image showing the marks below. Any ideas?

Is there any reason it would suddenly be clean, or at least not leave marks on images?
 
Dust usually only shows up at certain apertures, the image above is f/36 which you will rarely use in normal conditions.
the reason you probably havent seen them in your other photos is because the aperture will be much wider.
You need to send you camera off to have the sensor cleaned, or do it yourself by using a rocket blower or sensor swabs. Be Very carefull though, its easy to scratch the surface if the AA filter in front of the sensor if you arent carefull
 
looks like a dirty sensor to me.

The spots would be very noticible on clear backgrounds like the sky, you may not notice them say in a portrait
 
Looks like a dirty sensor, easy way to check just set your camera to the smallest aperture and take a photo of something plain white. Jessops are doing sensor cleaning pens for a fiver at the moment which i used on mine, little bit less daunting than a wet clean if you havent done it before.
 
Time for an Arctic Butterfly.
 
might be marks on your lens:thinking:
and if you have wiped it then that might explain pictures ok now ;)

No. Marks on your lens won't show up on the picture like that. It's stuff on the sensor, and it's only visible at small apertures (large f numbers).
