what do you mean by you can't use photos (bigger than 1MB). i just tried out a 15MB photo and i was able to reach upto the print preview page (i don't have a photo printer and so can't test if it actually prints, but its able to send the generated print page to the kde print system correctly and i would be surprised if it can't print that page).

Well I cannot. I can't see the preview if the image is bigger thant 1 MBytes 
and when I insert it into a month hoping it's going to insert it also if I 
cannot see it than I get this message: "No valid images selected for months
Click Back to select images".
What verison on kipiplugins are you using? I've got:

digikam 0.7.1beta2
digikamplugins 0.7.1beta2
kipi-plugins-0.1beta1
libkexif-0.2.1
libkipi-0.1

not taken from CVS. Do you need some screenshot to confirm this bug?

CVS commit by pahlibar: 


* the selection for the month url was being done only if a thumbnail could be
generated. if the image size happens to be larger than the user setting for
the preview data, the url was not being selected (as the thumbnail fails to 
generate). Fixed.
* Also use a generic image icon for the selected url till the thumbnail is
generated

The reason why your thumbnails are not showing is because your setting for the generating previews is lower than the size of the images you have. go to kcontrol->file manager->previews & meta-data-> and increase the "maximum file size" for which previews will be generated to a larger number (> than your maximum image size). there was an additional problem dependent on this which has been fixed.
