tech issues with photos i uploaded

[Tonyfish56]

First of all, it would be nice if they explained what was wrong instead of me wasting my time trying to figure out what they did not like about it! 

Second, I uploaded photos that olympus software measures in size around 50 megs where as photoshop measured them at around 10 megs. What i want to know is why when i uploaded the photos they were reduced in size to the low kbs i'm talking single digits?

First question: moderators don't have the time to post lengthy explanations why they rejected this or that picture. They give a hint, for you to look at your picture critically and to check what could lead to a rejection. If you do not find the reason, post it here and we will analyze the picture for you. After 10 rejections you will know where to look before uploading and how to analyze the rejected picture. It's a learning curve.

Your second question: You see only a preview of your picture, if you, as a buyer buy a picture, you get exactly what has been uploaded. So upload high quality pictures, because buyers expect those.
