I found a technical issue that many people may not be aware of, and that may impact the quality of their pictures to be viewed. Let me start with several scenarios:

 

(1) When the size of the upload picture is SMALLER than what the monitor can show, the original clarity is kept. No problem in this case.

 

(2) When the size of the upload picture is MUCH BIGGER than what the monitor can show, then the image quality will not be impacted much either, perhaps because there are a lot of data to help the computer to keep the picture clarity in resizing.

 

(3) The worst case is when the size is SLIGHTLY BIGGER than what the monitor can show. In this case, when the computer resizes the picture, the image losses its original clarity. That can be very frustrating, as all your hard work is not properly presented. This may because the computer needs to combine 1.n pixels into 1. It will impact architecture pictures (or images with straight or clearly defined outlines) more than others.

 

The trick part does not end here. If you upload a picture that is slightly smaller than what the monitor can show, it may look good after uploading, but when you open some menu bar on the right, the picture area become smaller and the computer may resize your picture, then the quality of the picture will degenerate. For example, I uploaded a picture with a size of 1400 pixels on horizontal side, and my monitor screen is 1920 X 1200, therefore the uploaded picture is OK when shown alone. However, if I open the info or some other optional menus, my picture is resized to give some space to the menu on the right. Then the picture looks murky. The same may happen when your picture is showing in the "Curate" section, where not all the space is for your picture but some is reserved for the comment and rating. This is pretty awful: when you need to show the best, you actually do not, and you may not even notice that because it is OK when uploaded. I got some comment pointing out the sharpness issue, it was until then when I noticed the problem caused by resizing.

 

I now want to share my finding with my on line friends. My suggestion is: make sure that after opening a menu on the right, your picture is still shown with its original resolution, or you need to upload a big size file to keep the clarity. It is especially so for images with sharp outlines.

 

Otherwise, I do not encourage uploading big size files, because that may waste the site's resource and also make the loading slow.

 

If any one has better understanding and solutions, please advise.
