Images show as uncompressed when they actually are compressed

After running a number of tests I cant find why images show as un-compressed when they really are.
For example there is one, out of many, image that the reported size is 294.7 KB, while actual size is 113.3 KB.

Here is the report:

Where are you seeing the actual size of 113.3KB from?

I also downloaded the file and verified that it is 294KB.

Thank you very much for your reply.

This is so weird.
Check out the screenshot attached.

It shows the direct url for the image on my browser and next to it View Image with the size of the file.

Yes that is a bit weird. Why do you feel the need to filter out your url in the image?
