HELP!...computer illiteracy!

I managed to ruin my entry to the 'reflection' comp.

When I read Dan's evaluation I didnt recognise the description of my pic which he said was essentially; "flat and soft"...!?!! When I looked at the entry I saw immediately what he meant and also that somewhere in the uploading process the image file reverted to the unedited original!

I only just managed to get my entry onto the site with 3 mins left before the midnight deadline, and then fell into bed completely exhausted from building stage scenary all day. Analysis has shown that the file lost it's editing between 'Picassa' and being exported into 'my pictures' ready for uploading to 'Photobucket' (the image in 'My pictures' is also soft and flat but that in Picassa is still showing my edits which were colour balancing and sharpening)

The whole pain of using this new K100D is getting the images thru the computer/software (which is now my own not very good PC at home) and at present I only have the time to really use Picassa, the pentax software being largely beyond my comprehension and endurance to succeed! Of neccessity at the moment my use of this camera is in stolen seconds and the pix sort of thrown at the computer late at night before collapsing.......

I would be very grateful for a bit of guidance..........

You might consider purchasing Photoshop Elements, particularily as it's on sale at present. It's a good balance of power and ease of use and can make the photo-editing process easier, including the preparation of files for web use.
