I upload the full size jpeg image. I don't resize for the web. Is export sharpness
a feature of flickr, or pp software? I'm only using dpp.
If you are uploading "full size" images to Flickr, then Flickr has to do a lot of "resizing" in order to display it at a "normal" Web-viewing size. So, if you aren't happy with those re-sized images, then it's up to you to size your images smaller for viewing...although if you have a reason for uploading a full-size "original" (like if you are providing large files for clients to get big prints) then your options may be limited...
Otherwise, DPP gives you the tools to resize in the Convert and Save and the Batch Process dialogs. You can resize to your chosen "pixel dimensions". For example, you can resize pics to the POTN limit of 1023 pixels at the widest dimension (although I'm not sure if you can do this with a "non-pro" Flickr account...? You can also use DPP to "play with" the final sharpness of an image...try resizing, Converting and Saving an image to a jpeg, open the smaller jpeg in the DPP editor, then applying some sharpening. If the result is better than what Flickr has been producing, then try uploading the resized image to Flickr.
It's true that Flickr will still resize your pics to produce the various "views", Thumbnails, Small, etc., but you will have more control over your outcome.
