Error uploading pictures

Hey I have found that even with this error, the image is uploaded.
Backout and then check your media, it may be there.
Especially when I am uploading to put into the post or make a thumbnail, I just back out and redo the image and in the GALLERY tab at the top it is in there.

Don’t know why, but it has been doing this for me many times.

Man, it is nuts. This has been my first dive well into WordPress. But it has shown me that this is a good setup, but confusing!

I may be missing something, but how I find it is inserting a photo into the post, then up at the top of the editor that opens, there is a GALLERY tab.

But when you use the HTML editor and click near the top to INSERT a photo , the dialog that opens has FROM COMPUTER FROM URL GALLERY and something else.

But anyways, I get that error message about every 4 or 5 uploads, then just cancelling the insert and then redoing it, I will see GALLERY (1) up at the top and sure enough, there is that pic! Also, when I look in the MEDIA files, I will see about 3 or 4 multiple copies of the pic I was getting an error message. So, I don’t get it. But I hope any of this info helps, I have had no luck with my questions, so it has been trial and error.
