Hello,

I use Delphi Seattle.
My customer loads pictures in database using Devexpress TcxImage component.
In this component they can "paste" pictures from a browser.

Later I need to make thumbnail picture of this. And this is the problem:

-my "thumbnail creation" procedure is for jpg image
-so it works well if it is a jpg but I get Jpeg error #53 if it is a png picture

Question: how can I detect at the beginning if it is a png picture (remember that I cannot know it if the customer uses paste from a browser) and how can I transform it in jpg image?

Thank you very much!
